[FRIAM] [Classified] SkewT/Appleman Chart Investigative research needing to estimate contrail formation on historical flight data

[Stephen Guerin]

Nick,

Your country needs you. Now is the time that we need to understand SkewT
diagrams for a visual investigation project. I can't say too much over
email as this is highly sensitive*, but if I have you a lat/long and
altitude, do you have a source of weather data to let me know if a contrail
would form and how long it would persist? We can start with Appleman

chart

but
perhaps you have better models. I'm really after the data sources give that
I have the flight track of a collection of aircraft. I'm trying to
disambiguate which flight it could be in a ground photo for which I don't
know exactly where or when it was taken.

This incident involves aircraft flying in earth's shadow at night time,
through civilian dawn and out of the shadow emerging into sunrise.
Classified Briefing: For your eyes only. here
<https://nextdoor.com/p/6yhKjXF7nWCr> is the mission dossier
<https://nextdoor.com/p/6yhKjXF7nWCr> where we need to confirm SEOUL-DFW
contrail emergence at the tail of this track. The plane is currently at the
head of the contrail.

* level of sensitivity and national importance may be exaggerated. mentions
of SkewT and applications of cloud nerdiness may be all that's necessary to
get Nick's attention
