But you don't even have to to do that. The first place you start, when seeing contrails is to check the ADDS weather page. There's a process, I do it every day and record it.

The combination of FE and ADDS is the elementary place to start. ADDS for the weather and FE to determine altitudes.
Both take a little time and study to learn. If anyone is willing, e-mail me.

Edited for one correction-

Mark said"high Chem11~ seems i have been a bit handicapped
i live in a commercial airway called
a "military operational area" MOA
that allows no commercial air traffic
so ALL my pictures taken around here are MIL
FA would do me no good or i would have"

This is a misunderstanding. There is a massive SUA out over the coast near Mark's location. Commercials fly through it as they fly through other SUA's. Somewhere on this board, I recall MAV or somebody explaining SUA's. There is more military activity in some areas than there are others and reasons for it.

ADDS is useful in determining if atmospheric conditions are conducive to persistent contrail formation. The Javascript is buggy however, so you might have to work at it; when I change the altitude parameters it routinely crashes my browser.

I use IE 5.5 and it works well for me most days. If it locks up or crashes, I disconnect and redial my ISP. Since they changed servers, it works much better and I am able to take captures for my journal in less than 15 minutes, where it used to take up to half an hour.

>>>I've checked ADDS maybe forty times over the course of the last year and the results were always the same. Too warm for persitent contrail formation and humidity was not a factor. And yet the sky was blanketed with trails that turned into artificial cirrus cover.<<<

If ADDS is showing humidity as low as 50%, then chances are it's high enough for contrail formation.* The temp in Florida at 30,000 feet is usually cold enough for trails, especially this time of year. On the other hand, locations north of the 41 degree latitude line will have temps low enough at 25,000 feet. ADDS is a fantastic learning tool and the only one I know available that demonstrates the variance of weather at different altitudes.

*Dr. Minnis is involved in the study of remote sensing of the atmosphere and the Earth's surface. His research focuses on the characterization and measurement of clouds, aerosols, and radiation for the study of climate.

I asked him WHY the ADDS pages will show relative humidity at values of 50%+ that correlate with reports of "chemtrails," (which in reality are nothing more than contrails.) Not being scientifically or meteorologically inclined, I assumed that the information from the ADDS pages was close to exact. It turns out I was wrong and technology hasn't advanced yet to the point I assumed it had. This is what Dr. Minnis clarified:

"Your notice about the 50% RH is typical. If you read the discussion on the web site, it talks about the humidity problems. There is a well-known bias in the relative humidities measured at high altitudes. The measurements are generally drier than the true value (based on research quality instruments vs operational ones). High altitude humidity was never a big factor in weather forecasts until recently. SO, people are trying come up with better operational measurement systems. When those measurements are put into a computer model to give values all over the country , it tends to reinforce the dry bias. That is why you get RH = 50% and contrails. The true value has to be greater than 100% for the contrails to persist for very long (more than a few minutes). At those cold temperatures, a small error in moisture measurement leads to a large error in RH. http://cdebsjournal.topcities.com/RHaltitude.htm

Currently, I find ADDS more reliable than the NASA Contrail Predictor. The Predictor in real time will mark areas where RH is present, even though it may be raining there. However, the archived data seems to be pretty darn close when compared with "chemtrail" reports for that date.

Morning flights begin each day on the East Coast. The mid area colors but the blues show the main and mostly used flight paths over the country. There are more flights flying over the colored areas other than the blues. As the morning progresses and the sun moves west, more flights take off.

Add to the East coast AM take-offs, the International flights arriving on the East Coast.

If I get up early enough Monday morning, I'll take captures from FE's North America Map and put it on a page so you can see the progression and increase in flights as the morning finds it's way west. If I'm not mistaken, the same concentration of flights will resemble the above.

Edited for stupidity...I see you are from Lansing! Small world, my best friend grew up there.

Could you please explain that map again? I'm not sure I understand why there are orange/red spots on the east and west sides of the country, but not in the middle. Don't planes have to fly over the middle of a jet route to get from one place to another? And why are cities like Milwaukee in the deep blue area of the map while Amarillo is in the yellow? Thanks for any enlightenment you can provide.
