With Preplexity's help generated a shell script that asses ice formation likelihood at 30000 feet:
produces an output file, contrail_predictions.csv, with timestamp, temperature at 300hPa, RH, RH ice, Favorable or Not Favorable for contrail formation:
...
- run plane-finder every minute or so. Identify any new planes that are above some elevation angle cutoff, say 15 degrees. Start a data file per plane in a folder for that night
- accumulate track information for each plane above threshold elevation angle.
- Use that track information and winds aloft to create contrail track for each plane. We can also predict this 5-10 min into the future.
- Use wind-aloft direction to determine contrail transport direction- is it along or cross-contrail? Make photometry assessment.
- send contrail mask file to scheduler.
- We can validate all this in daytime with all-sky Canon camera.
