3T3, this is strange! The URL you posted doesn't show up in your post for me, I can only see it if I click on edit! Thanks for the link  |

I'm not Lulu, but I don't think we know the altitude. That's why Rick picked 35,000 feet, the "usual" contrail altitude, to determine the humidity.
Does anybody know what the other numbers on his picture represent? The first column appears to be altitudes, but I can't figure out the rest. |

3T, LULU and anyone else who cares,
well this is a very important point. you cant just assume that the jet is at "a usual contrail altitude". what is a normal contrail altitide? there isnt one. there are a lot in the 30's but this is because there are alot of jets operating at these altitudes. how can you assume that the jet is at 35,000 ft? it could very easily be at 25,000 ft. what were the conditions at 25,000 ft?
my point is that conditions CAN vary wildly between levels. you might have a "RH" if 19% at 350 and a RH of 75% at 310. this happens. so unless you know the exact altitude of the aircraft the rest of this discussion is moot.
to me it seems that this person saw a trail. he then looked up the current conditions and found that at 35,000 the RH was 19. he then proclaims that the aircraft is at 350 for some unknown reason (jets do cruise at more than just one altitude you know)
hope this helps

See, guys? Dirk is right, which is why we have to get the data for all the different altitudes.
I'm trying to build a rangefinder. (Not easy when you don't have a single engineering neuron in your entire brain.) Is there some el-cheapo rangefinder we could use to at least get the distance of these trails? Chemtrailsorg listed some, but they were rather pricey. And I'm not sure what kind of rangefinder is good for 7 mile distances. |

And yes we could use the gold standard Flight Explorer if (1) we had the money and (2) it showed military planes. |

There's only two F/E 's that I know of, personal edtion...$9.95 per month...and the professional edtion...2 much 4 me....
basically the only difference is weather data, adds does that...
have at it...

I have to concur with Dirk as well 3T3, as my using the ADDS this AM showed varying RH for various altitudes, the upper most readings (40,000 and 45,000 feet showed 0%), other altitude levels varried considerably, thanks Dirk.

man, I'm so glad some of you are getting excited about the adds link, I hope that it will be used in conjunction with your studies of our skies...
but as of yet the only one's to make use of the tools before us F/E AND ADDS have been Thermit and chickie deb, scroll to the bottom of the page at the link below and you will see how long the adds link has been available...F/E even longer....

Happy skywatching...

Do you remember what approximately what they were, Lulu? The other factor is that the temperature needs to be -40° C or lower for persistent contrails, and that's hard to achieve in the summer at altitudes lower than 35,000 feet. |

You're right seeker! The thread was from before I joined, don't know how I missed it when reading through the older posts? I feel like a dolt! May I ask you why you have never used these tools in conjunction? or have you? |

lol..I have used them and still do Lulu...where do you think my ever so charming attitude about chemtrails comes from...
got a picture I'd like your opinion on...but will have to wait til later...I'm going to play kickball with the local ruffians !
