Here is something else. If aluminum particals are being sprayed, they have exactly the same chemistry as water. We have examples of Iridesense and Halos with the "chemtrails." I doubt aluminum refracts/difracts light the same as water. Nope. Not ready to buy that.

If aluminum particles were in jet fuel, then they would burn up in the combustion chambers. Ever throw an aluminum can into a camp fire? Watch what happens. It disintegrates into aluminum oxide ash. Hence your theory of aluminum in jet fuel to leave some aluminum trail is moot. At best, it would leave aluminum oxide particulates after combustion. No reason to put it in the fuel if it’s just going to burn up.
Now your links however, are referring to burning aluminum powder in ramjet engines. The purpose here is to use aluminum itself as the fuel, not to mix aluminum with jet A, or to introduce aluminum particulates into the atmosphere as you suggest, for the weather modification purposes you are implying.
Of course, if you noticed Gas, you would have realized this theory has already been de-bunked on countless occasions. Interesting that you seem to be ignoring this fact. |

Here's a theory to knock around . How about an open air Nazi Extermination Camp Death Camp and they don't have to try and hide the bodies,the families bury them. and foot bill, the whole cost.People getting colds that last for months,strange flus ,and other assorted illnesses{Plum Island}etc. More people dying sooner then need be. Sterilization to reduce population. The "einsteins" probably have an exact date to have the population reduced or????? |

Aluminum in the FUEL? That is plain crazy. I sure as heck wouldnt fly anything that has bits of aluminum in it, not to mention that the engines arent very fond of combusting it either. Like BJM said, once it goes into the engine, it wont come out anything like what it was before. So tell me another way they spray aluminum from the plane, will you? |

'If aluminum particles were in jet fuel, then they would burn up in the combustion chambers.'
Here we go, 'round and 'round.
How many times does it need to be pointed out that contrails are chemtrails. Hey don't take my word for it. Here's an excerpt from
'Aviation and the Global Atmosphere' - published by The Intergovernmental panel on Climate Change www.ipcc.ch
'Aerosol particles from aviation—comprising soot, metals, sulfuric acid, water vapor, and possibly nitric acid and unburned hydrocarbons—may influence the state of the atmosphere in many ways. ...'
3.2.3.2 Metal Particles
Aircraft jet engines also directly emit metal particles. Their sources include engine erosion and the combustion of fuel containing trace metal impurities or metal particles that enter the exhaust with the fuel (Chapter 7). Metal particles—comprising elements such as Al, Ti, Cr, Fe, Ni, and Ba—are estimated to be present at the parts per billion by volume (ppbv) level at nozzle exit planes (CIAP, 1975; Fordyce and Sheibley, 1975). The corresponding concentrations of 107 to 108 particles/kg fuel (assuming 1-mm radius; see below) are much smaller than for soot. Although metals have been found as residuals in cirrus and contrail ice particles (Chen et al., 1998; Petzold et al., 1998; Twohy and Gandrud, 1998), their number and associated mass are considered too small to affect the formation or properties of more abundant volatile and soot plume aerosol particles. '
Here is the on-line summary for policymakers. [url=http://www.ipcc.ch/pub/av(E).pdf]http://www.ipcc.ch/pub/av(E).pdf[/url]
The entire publication is no longer available on-line but here's the sections I copied a few months back
Aviation and the Global Atmosphere
3.1. Introduction
Recent advances in our understanding of heterogeneous chemistry in the lower stratosphere and the role of aerosols and clouds in climate forcing have increased the need to understand the influence of these aircraft emissions on atmospheric composition. Aerosol particles from aviation—comprising soot, metals, sulfuric acid, water vapor, and possibly nitric acid and unburned hydrocarbons—may influence the state of the atmosphere in many ways. These particles may provide surfaces for heterogeneous chemical reactions, both in the exhaust plume and on regional and global scales; represent a sink for condensable atmospheric gases; absorb or scatter radiation directly; and change cloud properties that may affect radiation indirectly. Persistent contrails can directly cause additional cirrus clouds to form. In addition, aerosol particles may enhance sedimentation and precipitation of atmospheric water vapor, hence affecting the hydrological cycle and the budget of other gases and particles. Changes in cloud formation properties and cloud cover may also affect actinic fluxes in the atmosphere and ultraviolet-B (UV-B) radiation at the surface.
3.2. Aerosol Emission and Formation in Aircraft Plumes
Aircraft jet engines directly emit aerosol particles and condensable gases such as water vapor (H2O), sulfuric acid (H2SO4), and organic compounds, which lead to the formation of new, liquid (volatile) particles in the early plume by gas-to-particle conversion (nucleation) processes. Other gas-phase species and charged molecular clusters (chemi-ions, or CIs) are also generated at emission, including nitric acid (HNO3) and nitrous acid (HNO2). Emission and formation of H2SO4 depend on fuel sulfur content, or sulfur emission index [EI(S)], and the conversion fraction of fuel sulfur to H2SO4. Formation of HNO3 and HNO2 depends on reactions of nitrogen oxides (NOx = NO + NO2) with hydroxyl radicals (OH). Particle formation depends on mixing of exhaust gases with ambient air, plume cooling rate, plume chemistry, and ambient aerosol properties. Soot particles formed during fuel combustion and emitted metallic particles constitute the solid (nonvolatile) particle fraction present in exhaust plumes. Under certain thermodynamic conditions, emitted water vapor condenses and freezes to form water-ice particles, thereby producing a condensation trail (contrail). These line clouds evaporate rapidly if the ambient humidity is low but may change the size and chemical composition of the remaining liquid aerosol particles. If the humidity is above ice saturation, contrails persist and grow through further deposition of ambient water.
An invisible aerosol trail is always left behind cruising aircraft. Aerosol and contrail formation processes in an aging plume determine the number, surface area, and mass of particles that are formed per mass of fuel consumed. Exhaust particle properties change in the presence of a contrail. Exhaust particle morphology and surface properties and aircraft-induced perturbations of background aerosol surface areas (Section 3.3) are of central importance for ozone changes caused by heterogeneous chemical reactions (Chapters 2 and 4). Particle number and freezing probability are key for the formation of ice (cirrus) clouds after passage of an aircraft in a region where otherwise no clouds would form (Section 3.4). Finally, aviation-produced aerosol can directly or indirectly influence the radiation budget of the atmosphere (Section 3.6 and Chapter 6). For recent reviews see Schumann (1996a), Fabian and Kärcher (1997), Friedl (1997), and Brasseur et al. (1998).
3.2.1.1. Water Vapor
Water vapor is present in aircraft exhaust in known amounts because the emission index is specified by the stoichiometry of near-complete fuel combustion (Chapter 7). Water vapor concentrations of a few percent at the engine exhaust nozzle far exceed the concentrations of other aerosol precursor gases. Ambient water vapor also participates in aerosol processes, with concentrations that vary widely depending on flight altitude and meteorological processes. Because of its abundance and thermodynamic properties, water vapor participates in nearly all aerosol formation and nucleation processes (e.g., Pruppacher and Klett, 1997).
3.2.1.2. Sulfur Species
Aviation fuels (kerosene) contain sulfur in trace amounts….
3.2.1.3. Chemi-ions
A large number of chemi-ions (CIs) are expected to be present in aircraft exhaust because ion production via high-temperature chemical reactions is known to occur in the combustion of carbon-containing (not necessarily sulfur-containing) fuels (e.g., Burtscher, 1992). In the jet regime, some recent models indicate that CIs effectively promote formation and growth of electrically charged droplets containing H2SO4 and H2O (Yu and Turco, 1997). In addition, CIs may contribute to the activation of exhaust soot. Positive ions include H3O+ and organic molecules like CHO+, C3H3+, and larger molecules (Calcote, 1983), whereas the free electrons rapidly attach to other molecules to form negative ions with sulfate and nitrate cores. Measurements of positive CIs in exhaust plumes are not available, and only very few in situ measurements of negative CIs are available to date. …
3.2.1.4 Nitrogen Species
The primary nitrogen emission from aircraft is in the form of NOx (Chapter 2).
…
3.2.1.5. Hydrocarbons
Aircraft engines emit non-methane hydrocarbons (NMHCs) as a result of incomplete fuel combustion. These species include alkenes (mostly ethene), aldehydes (mostly formaldehyde), alkines (mostly ethine), and a few aromates.
…
Aircraft also occasionally introduce hydrocarbons by jettisoning fuel at low altitudes in the troposphere. Most of the fuel evaporates while it falls to the ground (Quackenbush et al., 1994), which leads to a small increase of hydrocarbons in this region. Because of the small amounts of fuel released in this way, no essential impacts on atmospheric aerosols are expected.
3.2.2. Volatile Particles
3.2.2.1. Basic Processes
Volatile particles form in the exhaust plume of an aircraft as a result of nucleation processes associated with the emission of aerosol precursors (Hofmann and Rosen, 1978). Typical aerosol parameters in a young plume are included in Table 3-1 for reference. The newly formed particles grow by condensation (uptake of gaseous species) and coagulation (particles collide and attach) in the expanding plume. Coagulation processes involving charged particles originating from CI emissions are more effective because charge forces enhance collision rates. These processes are schematically presented in Figure 3-1. Key processes at young plume ages are determined mainly from the results of simulation models because of the lack of suitable plume measurements.
…
Once formed, the new volatile particles interact with nonvolatile and contrail ice particles through the processes of coagulation, freezing, condensation, and evaporation (Figure 3-1). Calculations show that the new liquid particles grow and shrink as a function of relative humidity, whereas H2SO4 molecules that enter the droplets stay in the liquid phase because of their very low saturation vapor pressure (Mirabel and Katz, 1974). They also suggest that volatile particles may take up HNO3 and H2O in the near field (Kärcher, 1996) to form particles with compositions similar to those found in cold regions of the stratosphere. These particles may persist in cold (< 200 K), HNO3-rich stratospheric air but will be short-lived (< 1 min) otherwise. As the plume continues to dilute with ambient air, abundant newly formed volatile particles remain at nanometer sizes and therefore add substantially to the overall aerosol surface area and abundance (Danilin et al., 1997). Their efficiency for heterogeneous chemistry and cloud formation, however, is size- and composition-dependent (Kärcher, 1997). They may be too small to act as efficient cloud- or ice-forming nuclei in the background atmosphere unless the air mass containing the aerosol is lifted or cooled or the relative humidity increases. Although studies exist on heterogeneous plume processing along selected trajectories (Danilin et al., 1994), systematic investigations of heterogeneous chemistry coupled to plume aerosol dynamics remain to be performed (Chapter 2).
Figure 3-2: Size distribution of various aerosol types present in young jet aircraft exhaust plumes (adapted from Kärcher, 1998a).
The evolution of volatile particles is significantly altered if a contrail forms. In contrails, volatile particles have to grow to sizes greater than about 100 nm via uptake of ambient H2O before most of them freeze (Section 3.2.4.2). As ice particles grow in size by deposition of H2O, they may also scavenge other volatile and soot particles (Anderson et al., 1998a,b; Schröder et al., 1998a). Thus, contrails are expected to contain fewer small particles than non-contrail plumes because of enhanced scavenging losses. After evaporation of contrail ice crystals, the residual volatile and soot cores remain as particles in the atmosphere (Figure 3-1). This contrail processing is expected to modify the particle size distribution and composition and may lead to efficient cloud condensation nuclei production (Yu and Turco, 1998b).
…
In situ measurements detailing particle volatility and size distributions such as those included in Figure 3-3 have involved relatively young plumes. Further observations in aging plumes (> 1 h) as they dilute with the background atmosphere are currently lacking. Without detailed observations of the microphysical evolution and chemical composition of volatile exhaust particles from the engine exhaust plume to the global scale, important uncertainties remain in assessing the potential global impact of exhaust products on chemistry and cloudiness.
3.2.3. Soot and Metal Particles
3.2.3.1. Soot
Aircraft jet engines directly emit solid soot particles. Soot encompasses all primary, carbon-containing products from incomplete combustion processes in the engine. Besides the pure (optically black) carbon fraction, these products may also contain nonvolatile (gray) organic compounds (e.g., Burtscher, 1992; Bockhorn, 1994). Soot parameters of importance for understanding plume processes are concentration and size distribution at the engine exit, nucleating and chemical properties, and freezing ability.
3.2.3.2 Metal Particles
Aircraft jet engines also directly emit metal particles. Their sources include engine erosion and the combustion of fuel containing trace metal impurities or metal particles that enter the exhaust with the fuel (Chapter 7). Metal particles—comprising elements such as Al, Ti, Cr, Fe, Ni, and Ba—are estimated to be present at the parts per billion by volume (ppbv) level at nozzle exit planes (CIAP, 1975; Fordyce and Sheibley, 1975). The corresponding concentrations of 107 to 108 particles/kg fuel (assuming 1-mm radius; see below) are much smaller than for soot. Although metals have been found as residuals in cirrus and contrail ice particles (Chen et al., 1998; Petzold et al., 1998; Twohy and Gandrud, 1998), their number and associated mass are considered too small to affect the formation or properties of more abundant volatile and soot plume aerosol particles.
3.3.3. Observations of Aircraft-Produced Aerosol and Sulfate Aerosol Changes
Observations of aircraft-induced aerosols have increased substantially in recent years (see Section 3.2). Concentrations of aerosol particles and aerosol precursor gases well above background values have been observed in the exhaust plumes of aircraft operating in the upper troposphere and lower stratosphere. Although aircraft emissions are quickly diluted by mixing with ambient air to near background values, the accumulation of emissions in flight corridors used in the routing of commercial air traffic has the potential to cause notable atmospheric changes.
3.2.4. Contrail and Ice Particle Formation
3.2.4.1. Formation Conditions and Observations
Contrails consist of ice particles that mainly nucleate on exhaust soot and volatile plume aerosol particles. Contrail formation is caused by the increase in relative humidity (RH) that occurs in the engine plume as a result of mixing of warm and moist exhaust gases with colder and less humid ambient air (Schmidt, 1941; Appleman, 1953). The RH with respect to liquid water must reach 100% in the young plume behind the aircraft for contrail formation to occur (Höhndorf, 1941; Appleman, 1953; Busen and Schumann, 1995; Jensen et al., 1998a). The thermodynamic relation for formation depends on pressure, temperature, and RH at a given flight level; fuel combustion properties in terms of the emission index of H2O and combustion heat; and overall efficiency h (Cumpsty, 1997). h, defined as the fraction of fuel combustion heat that is used to propel the aircraft, can be computed from engine and aircraft properties (Schumann, 1996a; see also Section 3.7). Only the fraction (1-h) of the combustion heat leaves the engine with the exhaust gases. As the value of h increases, exhaust plume temperatures decrease for a given concentration of emitted water vapor, hence contrails form at higher ambient temperatures and over a larger range of altitudes in the atmosphere (Schmidt, 1941). Several recent studies reported formation and visibility of contrails at temperatures and humidities as predicted by thermodynamic theory for a variety of aircraft and ambient conditions (Busen and Schumann, 1995; Schumann, 1996b; Schumann et al., 1996; Jensen et al., 1998a; Petzold et al., 1998). These data are compiled in Figure 3-4. The mixing process in the expanding exhaust plume is close to isobaric, so the specific excess enthalpy and water content of the plume decrease with a fixed ratio as plume species dilute from engine exit to ambient values. Hence, plume conditions follow straight “mixing lines” in a plot of H2O partial pressures versus temperature (Schmidt, 1941) (Figure 3-4). The thermodynamic properties of H2O are such that the saturation pressures over liquid water and water-ice (solid and dashed lines) increase exponentially with temperature. Therefore, within the first second in the plume, the exhaust RH increases to a maximum, then decreases to ambient values. The ambient temperature reaches threshold values for contrail formation when the mixing lines touch the liquid saturation curve in Figure 3-4b. Contrails persist when mixing-line endpoints fall between the liquid and ice saturation pressures—that is, when the ambient atmosphere is ice-supersaturated. Without ambient ice supersaturation, contrail ice crystals evaporate on time scales of seconds to minutes. Short-lived contrails may also form without ambient water vapor if ambient temperatures are sufficiently low.
Contrails become visible within roughly a wingspan distance behind the aircraft, implying that the ice particles form and grow large enough to become visible within the first tenths of a second of plume age. Ice size distributions peak typically at 0.5 to 1 µm number mean radius (Figure 3-2). A lower limit concentration of about 104 cm-3 of ice-forming particles in the plume (at plume ages between 0.1 and 0.3 s) is necessary for a contrail to have an optical depth above the visibility threshold (Kärcher et al., 1996b). These values and the corresponding mean radii of 1 µm of contrail ice particles are in agreement with in situ measurements in young plumes (Petzold et al., 1997). Initial ice particle number densities increase from 104 to 105 cm-3 and mean radii decrease from 1 to 0.3 µm when the ambient temperature is lowered by 10 K from a typical threshold value of 222 K (Kärcher et al., 1998a). Although aerosol and ice particle formation in a contrail are influenced by the fuel sulfur content (Andronache and Chameides, 1997, 1998), it has only a small (< 0.4 K) impact on the threshold temperature for contrail formation (Busen and Schumann, 1995; Schumann et al., 1996).
…
Contrail ice crystals evaporate quickly when the ambient air is subsaturated with respect to ice, unless the particles are coated with other species such as HNO3 (Diehl and Mitra, 1998). Simulations suggest that a few monolayers of HNO3 may condense onto ice particle surfaces and form NAT particles in stratospheric contrails (Kärcher, 1996). These particles would be thermodynamically stable and longer lived and would cause a different chemical perturbation than would short-lived stratospheric contrails composed of water ice. However, the relevance of this effect on larger scales has not yet been studied because no parameterization of NAT particle nucleation in aircraft plumes exists for use in atmospheric models (Chapter 4).
3.3.6. Polar Stratospheric Clouds and Aircraft Emissions
During winter in the polar regions, low temperatures lead to the formation of polar stratospheric cloud (PSC) particles, which contain H2SO4, HNO3, and H2O (e.g., WMO, 1995; Carslaw et al., 1997; Peter, 1997). PSCs activate chlorine, leading to significant seasonal ozone losses in the lower stratosphere, particularly in the Southern Hemisphere (WMO, 1995). PSC formation may be enhanced by the atmospheric accumulation of aircraft emissions of NOx, H2O, and sulfate, as well as through direct formation in aircraft plumes in polar regions (Section 3.2 and Chapter 4). If aircraft emissions change the frequency, abundance, or composition of PSCs, the associated ozone loss may also be modified (Peter et al., 1991; Arnold et al., 1992; Considine et al., 1994; Tie et al., 1996; Del Negro et al., 1997).
3.4. Contrail Occurrence and Persistence and Impact of Aircraft Exhaust on Cirrus
Aircraft cause visible changes in the atmosphere by forming contrails that represent artificially induced cirrus clouds.
3.4.1. Cirrus and Contrails
Ice crystal number densities are limited by competition between increasing saturation as a result of cooling in vertical updrafts and decreasing saturation as a result of growth of ice crystals. The depletion of vapor as a result of growth of the first few ice crystals nucleated prevents further ice nucleation on the remaining particles (Jensen and Toon, 1994). Once ice crystals form and take up available water vapor, supersaturation declines and further nucleation of ice ceases. This selectivity causes ice crystals in cirrus to be larger relative to droplets in liquid water-containing clouds—apart from differences in saturation vapor pressures over ice compared to water, which causes more water vapor to be available for deposition on ice particles than on water droplets. Large ice particles may precipitate rapidly. Many cirrus clouds have a “fuzzy” appearance because rapid precipitation causes optically thin edges of clouds to be diffuse, and precipitation allows particles to spread in the wind, forming long tails of cloud. Ice crystal nucleation also depends on available aerosol in the upper troposphere, the properties of which are only poorly known (Ström and Heintzenberg, 1994; Podzimek et al., 1995; Sassen et al., 1995; Schröder and Ström, 1997). In some locations, upper tropospheric particles are dominated by sulfates (Yamato and Ono, 1989; Sheridan et al., 1994). However, more recent data show that minerals, organic compounds, metals, and other substances may often be present in significant quantities (Chen et al., 1998; Talbot et al., 1998).
…
Persistent contrail formation requires air that is ice-supersaturated (Brewer, 1946). Ice-supersaturated air is often free of visible clouds (Sassen, 1997) because the supersaturation is too small for ice particle nucleation to occur (Heymsfield et al., 1998b). Supersaturated regions are expected to be quite common in the upper troposphere (Ludlam, 1980). The presence of persistent contrails demonstrates that the upper troposphere contains air that is ice-supersaturated but will not form clouds unless initiated by aircraft exhaust (Jensen et al., 1998a). Aircraft initiate contrail formation by increasing the humidity within their exhaust trails, whereas local atmospheric conditions govern the subsequent evolution of contrail cirrus clouds. Indeed, the ice mass in long-lasting contrails originates almost completely from ambient water vapor (Knollenberg, 1972).
Ice-supersaturated air masses are often formed when ice-saturated air masses are lifted by ambient air motions. While the air lifted, it may remain cloud-free until it is cooled adiabatically to near-liquid saturation (Ludlam, 1980). Other evidence for large supersaturation occurring in the upper troposphere is provided by cirrus fallstreaks that grow while falling through supersaturated air layers (Ludlam, 1980) and by a few localized humidity measurements (Brewer, 1946; Murphy et al., 1990; Ovarlez et al., 1997; Heymsfield et al., 1998b). Recent humidity measurements by commercial aircraft show that—in flights between Europe, North and South America, Africa, and Asia—14% of flight time was in air masses that were ice-supersaturated with a mean value of 15% (Helten et al., 1998; Gierens et al., 1999).
3.4.3. Contrail Occurrence
Aged contrails often cannot be distinguished from cirrus, which poses an observational problem in determining the frequency and area of coverage by contrails. An important example of the persistence of contrails and their evolution into more extensive cirrus is shown in Figure 3-13. An initial oval contrail observed in GOES-8 satellite images diffused as it was advected over California until it no longer resembled its initial shape 3 h later (Minnis et al., 1998a). The exhaust from this single aircraft flying for less than 1 h in a moist atmosphere caused a cirrus cloud that eventually covered up to 4,000 km2 and lasted for more than 6 h. Other contrails and contrail clusters were observed to develop over periods of 7 to 17 h, spreading to cover areas of 12,000 to 35,000 km2. Such dispersed contrails are usually indistinguishable from natural cirrus; hence, satellite detection algorithms based on the linear structures of young contrails will not detect these dispersed contrails.
3.4.5. Impact of Aircraft Exhaust on Cirrus Clouds and Related Properties
Aircraft may perturb natural cirrus through the addition of water vapor, soot, and sulfate particles and by inducing vertical motions and turbulent mixing (Gierens and Ström, 1998). Observations of cirrus coverage in certain regions have found perturbations from anthropogenic aerosol (Ström et al., 1997). Persistent contrails are often associated with or embedded in natural cirrus (Minnis et al., 1997; Sassen, 1997). Such in-cloud contrails may be formed slightly above the Schmidt-Appleman temperature threshold because ambient ice particles that enter the engine inlet increase the humidity in the exhaust plume (Jensen et al., 1998a; Kärcher et al., 1998a). Some evidence associates in-cloud contrails with regions of enhanced absorbing material and enhanced ice crystal number densities (Ström and Ohlsson, 1998). The presence of HNO3 may increase the hygroscopic growth of supercooled cloud droplets (Laaksonen et al., 1997), and HNO3 dissolved in sulfate solution droplets may change their freezing behavior. The importance of such perturbations has not been quantified.
Soot particles originating from aircraft exhaust may act as freezing nuclei. In an atmosphere with few freezing nuclei, this perturbation could lead to an expansion of cirrus cover, a change in average particle size, and related changes in cloud surface area and optical depth (Jensen and Toon, 1997)—hence have consequences for radiative forcing (see Section 3.6.5).
…
Aircraft measurements in and near clouds have indicated the presence of light-absorbing material contained inside ice crystals. The distribution pattern and the amount of measured absorbers suggest that the material is related to aircraft soot (Ström and Ohlsson, 1998) (Figure 3-17).
…
Sedimentation of large particles in persistent contrails may remove water vapor from the upper troposphere, possibly reducing radiative heating by water vapor, and cause seeding of lower level clouds (Murcray, 1970; Knollenberg, 1972). Sedimentation of ice crystals, which has been observed occasionally (Konrad and Howard, 1974; Schumann, 1994; Heymsfield et al., 1998a), becomes important only in strongly supersaturated air (Hauf and Alheit, 1997) when large ice crystals form and have the potential to fall through lower-lying saturated air in which they will not evaporate readily. Because no attempts have been made to quantify the precipitation rate from contrails, the significance of this precipitation has not been assessed.
3.5. Long-Term Changes in Observed Cloudiness and Cloud-Related Parameters
Contrails have long been considered possible modifiers of regional climate (Murcray, 1970; Changnon, 1981). Contrails may increase total cloud and cirrus cloud amounts, and consequently change the Earth’s radiation balance. As a result, surface and upper tropospheric temperatures may change (Detwiler, 1983; Frankel et al., 1997). …
3.5.2. Changes in Other Climate Parameters
A substantial decrease in diurnal surface temperature range (DTR) has been observed on all continents (Karl et al., 1984; Rebetez and Beniston, 1998). The reasons for this decrease are not clear; it could be caused by a change in aerosol burden, cloud amount, cloud ceiling height (Hansen et al., 1995), soil moisture, or absorption of solar radiation by increased water vapor in the atmosphere (Roeckner et al., 1998).
3.6. Radiative Properties of Aerosols, Contrails, and Cirrus Clouds
Aircraft emissions have an impact on the Earth’s radiation budget and climate through direct and indirect changes in aerosols and cloudiness. Recent climate assessments have stressed the importance of natural and anthropogenic changes in aerosols on direct radiative forcing (Charlson et al., 1990; Schwartz, 1996). Aerosols and contrails have direct effects (scattering and absorbing solar and longwave radiation) and indirect effects (modifying the formation of cloud particles and radiative properties of clouds). Several studies have addressed the direct impact of contrails (e.g., Detwiler and Pratt, 1984; Grassl, 1990; Liou et al., 1990; Sassen, 1997). The indirect effect of contrails has not yet been investigated in detail. The direct radiative impacts of aircraft soot emissions (Pueschel et al., 1992, 1997) and sulfate aerosol have been evaluated as being small (Friedl, 1997; Brasseur et al., 1998). The indirect radiative effect of aircraft-induced aerosols on clouds is essentially unknown. In fact, the indirect radiative effect of non-aviation aerosol has been studied for liquid water clouds (IPCC, 1996), but the indirect effect of changing cirrus is not yet known either. Here, the discussion focuses on the impact of aircraft-generated aerosol and that of contrails and changed cirrus clouds.
3.6.5. Radiative Impact of Additional or Changed Cirrus and Other Indirect Effects
Aircraft emissions may also change the properties of natural cirrus clouds (see Section 3.4.5). In a high-traffic region, cirrus was found to be affected by soot emissions from aircraft, causing an approximate doubling of the ice particle concentration (Ström and Ohlsson, 1998). Smaller particles cause larger optical depth for constant ice water content. Radiative forcing is strongly sensitive to particle size (see Table 3-7). As Figure 3-20 indicates, an increase in optical depth causes additional heating if the cirrus cloud was optically thin but cooling if it was optically thick (Wyser and Ström, 1998). One recent study suggests that the indirect heating effect of aviation-induced changes in cirrus ice particle number density for fixed cloud cover may be positive and comparable to or even larger than that from increases in cloud cover (Meerkötter et al., 1999).
3.7. Parameters of Future Changes in Aircraft-Produced Aerosol and Cloudiness
The future effects of aircraft depend on trends in climate and air traffic amount and changes in the technical properties of aircraft. Our current understanding of the formation of aviation-induced aerosol and cloudiness can be used to estimate how future changes may affect the impacts of aviation and to identify mitigation options that would be effective in reducing these impacts.
3.7.1 Changes in Climate Parameters
If climate change occurs in the future, atmospheric parameters related to aerosols and contrails will also have changed. Of particular importance to aviation-induced aerosol and cloudiness are changes in temperature and humidity in the upper troposphere and lower stratosphere; changes in the height, temperature, and humidity of the tropopause region; changes in the abundance of particles; and changes in cloudiness. Table 3-10 summarizes how changes in these parameters may be reflected in aviation-related impacts. General circulation models of the atmosphere predict that the climate of 2050 will reflect global warming from the accumulation of greenhouse gases. In this new climate, models predict increases in the amounts of cirrus clouds, the height of the tropopause, and upper tropospheric temperature (IPCC, 1996; Timbal et al., 1997). A higher tropopause would cause more contrails, at least at high latitudes. Observed temperature changes (e.g., Parker et al., 1997) do not reveal the expected temperature increase in the upper troposphere. Some models predict a higher tropopause if the surface temperature increases (about 200-m altitude increase for 1 K surface temperature increase) (Thuburn and Craig, 1997). Increases on the order of 100 m were analyzed in polar regions and at mid-latitudes (Hoinka, 1998; Steinbrecht et al., 1998). Such changes may be forced by cooling of the lower stratosphere as a result of changes in ozone concentration (Hansen et al., 1997) and increases in moisture as a result of increasing methane concentrations. Stratospheric temperatures between 50 and 100 hPa have decreased by about 1 to 2 K since 1980 (Ramaswamy et al., 1996; Halpert and Bell, 1997). An increase in water vapor concentration has been observed in the lower stratosphere, with the largest trend (0.8%/yr) in the 18- to 20-km region (Oltmans and Hofmann, 1995). Because few contrails currently form in the lower stratosphere, small changes in stratospheric conditions will not create significant changes in contrail abundance. Aerosol loading in the troposphere and lower stratosphere may increase because of changed climate conditions and increased surface emissions. Surface emissions from fossil fuel burning were projected to grow by a factor of 1.5 to 2.1 from 1990 to 2040 (Wolf and Hidy, 1997).
6.1.2. Aircraft-Induced Climate Change
Aircraft emissions are expected to modify the Earth’s radiative budget and climate as a result of several processes (see also Figure 6-1): emission of radiatively active substances (e.g., CO2 or H2O); emission of chemical species that produce or destroy radiatively active substances (such as NOx, which modifies O3 concentration, or SO2, which oxidizes to sulfate aerosols); and emission of substances (e.g., H2O, soot) that trigger the generation of additional clouds (e.g., contrails).
rainheart- So now that we are all understanding that contrails ARE chemtrails and that they DO have a direct effect on climate and the Earth's ecology, here's a little reading providing the motive for intentional climate and environmental change.

We express our appreciation to Mr Mike McKim of Air War College who provided a wealth of technical expertise and innovative ideas that significantly contributed to our paper. We are also especially grateful for the devoted support of our families during this research project. Their understanding and patience during the demanding research period were crucial to the project's success.
Executive Summary
In 2025, US aerospace forces can "own the weather" by capitalizing on emerging technologies and focusing development of those technologies to war-fighting applications. Such a capability offers the war fighter tools to shape the battlespace in ways never before possible. It provides opportunities to impact operations across the full spectrum of conflict and is pertinent to all possible futures. The purpose of this paper is to outline a strategy for the use of a future weather-modification system to achieve military objectives rather than to provide a detailed technical road map.
A high-risk, high-reward endeavor, weather-modification offers a dilemma not unlike the splitting of the atom. While some segments of society will always be reluctant to examine controversial issues such as weather-modification, the tremendous military capabilities that could result from this field are ignored at our own peril. From enhancing friendly operations or disrupting those of the enemy via small-scale tailoring of natural weather patterns to complete dominance of global communications and counterspace control, weather-modification offers the war fighter a wide-range of possible options to defeat or coerce an adversary. Some of the potential capabilities a weather-modification system could provide to a war-fighting commander in chief (CINC) are listed in table 1.
Technology advancements in five major areas are necessary for an integrated weather-modification capability: (1) advanced nonlinear modeling techniques, (2) computational capability, (3) information gathering and transmission, (4) a global sensor array, and (5) weather intervention techniques. Some intervention tools exist today and others may be developed and refined in the future.

Detect Hostile Weather Activities Defend against Enemy Capabilities
Current technologies that will mature over the next 30 years will offer anyone who has the necessary resources the ability to modify weather patterns and their corresponding effects, at least on the local scale. Current demographic, economic, and environmental trends will create global stresses that provide the impetus necessary for many countries or groups to turn this weather-modification ability into a capability.
In the United States, weather-modification will likely become a part of national security policy with both domestic and international applications. Our government will pursue such a policy, depending on its interests, at various levels. These levels could include unilateral actions, participation in a security framework such as NATO, membership in an international organization such as the UN, or participation in a coalition. Assuming that in 2025 our national security strategy includes weather-modification, its use in our national military strategy will naturally follow. Besides the significant benefits an operational capability would provide, another motivation to pursue weather-modification is to deter and counter potential adversaries.
In this paper we show that appropriate application of weather-modification can provide battlespace dominance to a degree never before imagined. In the future, such operations will enhance air and space superiority and provide new options for battlespace shaping and battlespace awareness.1 "The technology is there, waiting for us to pull it all together;"2 in 2025 we can "Own the Weather."
Chapter 1
Introduction
Scenario: Imagine that in 2025 the US is fighting a rich, but now consolidated, politically powerful drug cartel in South America. The cartel has purchased hundreds of Russian-and Chinese-built fighters that have successfully thwarted our attempts to attack their production facilities. With their local numerical superiority and interior lines, the cartel is launching more than 10 aircraft for every one of ours. In addition, the cartel is using the French system probatoire d' observation de la terre (SPOT) positioning and tracking imagery systems, which in 2025 are capable of transmitting near-real-time, multispectral imagery with 1 meter resolution. The US wishes to engage the enemy on an uneven playing field in order to exploit the full potential of our aircraft and munitions.
Meteorological analysis reveals that equatorial South America typically has afternoon thunderstorms on a daily basis throughout the year. Our intelligence has confirmed that cartel pilots are reluctant to fly in or near thunderstorms. Therefore, our weather force support element (WFSE), which is a part of the commander in chief's (CINC) air operations center (AOC), is tasked to forecast storm paths and trigger or intensify thunderstorm cells over critical target areas that the enemy must defend with their aircraft. Since our aircraft in 2025 have all-weather capability, the thunderstorm threat is minimal to our forces, and we can effectively and decisively control the sky over the target.
The WFSE has the necessary sensor and communication capabilities to observe, detect, and act on weather-modification requirements to support US military objectives. These capabilities are part of an advanced battle area system that supports the war-fighting CINC. In our scenario, the CINC tasks the WFSE to conduct storm intensification and concealment operations. The WFSE models the atmospheric conditions to forecast, with 90 percent confidence, the likelihood of successful modification using airborne cloud generation and seeding.
In 2025, uninhabited aerospace vehicles (UAV) are routinely used for weather-modification operations. By cross-referencing desired attack times with wind and thunderstorm forecasts and the SPOT satellite's projected orbit, the WFSE generates mission profiles for each UAV. The WFSE guides each UAV using near-real-time information from a networked sensor array.
Prior to the attack, which is coordinated with forecasted weather conditions, the UAVs begin cloud generation and seeding operations. UAVs disperse a cirrus shield to deny enemy visual and infrared (IR) surveillance. Simultaneously, microwave heaters create localized scintillation to disrupt active sensing via synthetic aperture radar (SAR) systems such as the commercially available Canadian search and rescue satellite-aided tracking (SARSAT) that will be widely available in 2025. Other cloud seeding operations cause a developing thunderstorm to intensify over the target, severely limiting the enemy's capability to defend. The WFSE monitors the entire operation in real-time and notes the successful completion of another very important but routine weather-modification mission.
This scenario may seem far-fetched, but by 2025 it is within the realm of possibility. The next chapter explores the reasons for weather-modification, defines the scope, and examines trends that will make it possible in the next 30 years.

If I was a debunker I would simply tell people that yes, indeed, contrails contain heavy metals, chemi-ions, soot particles, etc, etc.
And that yes, these contrails do cause climate change.
Everything else is just a coincidence and/or speculation.
But I guess if we are presented with such an explanation then it would follow that there would be a call for reduced air-traffic, environmental impact assessments, health studies, increased air quality monitoring, etc.
I figure either the atmosphere has changed humidity composition drastically over the last few years from a result of climate change (intentional or not) resulting in increased presence of persistent chemtrails (in which case we should all be VERY concerned to witness the markers of total climate and atmospheric change), or what we are seeing is no accident at all.
I sure wish the chemtrail debunkers had the sense to actually research this issue.

Rainheart; Don't waste your time and breath with depunkers, they know very well that there are multipurpose reasons for spewing out sky garbage. They have the attitude "My country right or wrong". They have no regard for the consquences to humanity, wildlife, air, water,soil. Remember what happened in Tennesee to the birds unlucky to have been on the property of a radio broadcasting station when Haarp was experimenting with their electrical power. The equipment at that station was fried. And even worse the birds were fried, pictures of them were posted on this site. Some dead, some wandering about with burned feathers and legs, some dropping out of the sky. They got away with it, no accusations against the culprits.***You don't need to prove anything to depunkers***Now back to Chemtrails, let them get samples of sky crap and take it to an independant lab. and post it to prove to us there's nothing but ice crystals in our atmosphere. Notice, this web site is called Chemtrail Central, not, No Chemtrail Central. Debunkers don't respond, not the least bit interested in anything you have to say.

Thanks Jeanie, I usually resist the urge to play this game. But, it gave me an opportunity to dig that stuff up again, who knows, some folks might get something out of it.
Can you give me more of a clue to find the story on the Tennesee fried radio birds?

MYSTERY IN HARTSVILLE
At about 10:45 AM Friday, radio station WJKM and CMR (Country Music Radio), with studios in Hartsville, Tennessee was knocked off the air by a very powerful strange energy blast! There was a crystal clear blue sky, no clouds or rain. It was not lightning!
1.All the radio station's lines were knocked out.
2. Several power transformers were blown several blocks away from the studios (smoke seen billowing out of one)
3. All phone lines at the newspaper (The Hartsville Vidette), the local farm co-op and all other phones in this small radius were knocked out!
4. Radio station transmitter lost all MOSFETS and the output - tuning network.
5. All computers at WJKM lost motherboards, network cards etc.
6. ISDN was knocked out.
7. Most all the equipment Zephyr codec and EAS all knocked out.
THERE WAS NOT A CLOUD IN THE SKY! This was not lightning!
In the back of the radio station were DEAD FRIED BIRDS! Their wings, tails and feet severely burned. Station secretary Jennifer and sales manager Steve found a small bird still alive hopping around with its wings and tail feathers burned off. Many of the birds were still alive but badly burned.
These are smaller birds. The wingspan is not large enough for them to get fried from getting across a powerline to ground. This was not just one bird.
Steve (sales manager) told me he heard a loud electrical overload sound then the power went out. He told me he has never heard anything like this ever in his life. There was no blown transformer near the radio station. The closest burned transformer was at least three city blocks from the building.
The editor of the Vidette said she was sitting with her back to the window. She heard a loud roaring sound like an overload and something came through the window and a flash of light went through the entire building. The Vidette is next door to the radio station.
The Power Company, Tri County Electric and Bell South seem to be at a loss to explain the situation.
This is not the first time WJKM has had strange power surge problems. It has been difficult to keep computers up and running at the Hartsville studios and transmitter site.
We have called the local power company and complained to no avail. They seem to be as puzzled by the problem as we are. They have placed monitoring equipment on the lines and have seen nothing unusual.
Yet in this outage the editor of the Vidette told me she keeps all the computers in the building unplugged. The newspaper publishes once a week so they only plug the computers into power once a week. Friday the Editors calculator was plugged into the wall outlet and it was destroyed by the surge.
These surges are not just coming into the power lines. They are also entering the radio station through phone lines and the antenna system. This is evident in blown telephone equipment. Sometimes the equipment is not destroyed but the program settings are scrambled or wiped out.
We have surge protectors plugged into surge protectors. We keep MOV's by the boxfulls.
We have been at a loss to make a determination as to the cause of these surges. The only clue as to what the cause may be has been suggested by our listeners.
Many of the callers to the radio station seem to think that there is some sort of activity at the old Hartsville nuclear power plant site. My first trip to the site left me a bit cold as the place looks like an abandoned ghost town. With heaps of things lying around, it looks like a good set for a futuristic movie.
The nuclear power plant is a site that cost the general public millions of dollars that was supposedly never finished. The construction of the plant came to an abrupt halt some years back leaving the community devastated. TVA (Federal Government) will tell you it is being used as a storage area only. Yet I have calls at the radio station from listeners who claim to hear strange humming sounds coming from the location. Listeners have seen strange objects overhead. Listeners have claimed to see triangular shaped craft overhead. Silent black helicopters at all hours of the night. Huge military C-130's heading in as if to land or leaving the area nose up as if they have just taken off.
There are no visible places for a C-130 to land or take off. We have searched the area as well as we could.
Listeners from the area have called talking about a strange humming sound. Comments like "you can feel it" "It makes the hair stand up on your neck" are common. We also hear that you can't locate the source of the humming it seems to be coming from everywhere. This has been mentioned only by people who live near the nuclear power plant site. . A rural elderly listener called my morning show extremely upset. He told us he had lost several beagle puppies in the area. A friend of his told him that he thought that he had seen the pups in the area near the cooling tower. He reported to us in a phone call that he had driven his truck to the area. He thought he was hearing the beagles out in the wooded area so he climbed over the fence and started calling to them. He told us he was greeted with an overhead helicopter and a ground force of about 30 people. They allegedly escorted him off the property in a very rough and crude manner. He said they were some kind of police, some in plain clothes. He told us they were rude and threatening.
A listener who is a tech that lives on a hill near the area has had fluorescent bulbs light in his hand on various spots on his property. He discovered this by accident but has witnesses to the phenomenon. He works with surveillance cameras, thermal imaging and a lot of high tech stuff. He tells us there is operational radar being used at the nuclear site at different times.
A Hartsville resident who's ex-husband worked at the site tells us that there is a reactor there. We have had several reports of this from different folks in the community. She tell us that her husband was told "don't eat the fish from the river or eat any deer shot in the area"
Our local heating and air conditioning contractor tells about how he sees large shinny new 18 wheel tankers go and come from the nuclear site at 3 in the morning.
A gentleman who is a relative to an owner of a local grocery establishment claims to have seen a Bigfoot near the nuclear plant.
It is also interesting that according listeners have called in, there has apparently been an increase in what they are calling fibromyalgia. This is a decease name appointed to the unexplainable severe and disabling pain throughout the entire body over recent years, as well as, an increase in headaches mimicking migraines that are not actual migraines.
At night the entire area has a strange chemical smell to it somewhat pungent like ozone and chemicals. The radio station transmitter and Hartsville studio is located in the middle of Hartsville City Park about 5 miles from the nuclear cooling tower.
We are in no way accusing the TVA or the nuclear power plant of causing this problem. We are just reporting what listeners and residents of the community have reported to us.
One thing that we do find strange is this, in the beginning we would go on the air and joke about the nuclear power plant. We did this because of the TVA's vague promise to turn a good portion of the land back to the community for development. This was always talked about but nothing ever happened. We placed several calls to TVA. No one ever responded. When we would get on the air and start airing some of these reports it was always promptly followed by a press release or a public meeting about the donation of the land back to the county. We were told not to talk about it, that the TVA would get upset. Whenever we would stop talking about it, then it seemed that you would hear nothing about the land development. We have been off the subject for a good time now. Their latest announcement is to develop the land in partnership with the local Power Company for an industrial power park. They say this wont happen now for 4 years. They now claim they must do a 4 year environmental study. What do they need to study? Was there not a study done in order to build a nuclear facility? What else needs to be studied for a commercial business site? For you the listener, thank you for putting up with our outage. We are making repairs as fast as we can. As for the cause, we have no idea what this is all about. We are concerned about the charred and fried birds however. These birds were found on our property in areas where there are no powerlines! The Power Company said the birds got into a power transformer. What transformer? Our 10 KVA pole peg behind the radio station? How would all these birds do that? After being in or near the transformer, how did they all get to different locations around the 5 acres of land where there are no power lines? If the birds were sitting on an electrical wire and were hit by a surge their legs would have been burned off! These birds have legs. Its their wings and feathers that are burned, singed or missing! It appears to us these birds were cooked in flight! But by what
