    Calculator for RHi and Contrail Persistence Criteria

    . I've started on a calculator to convert RHw (relative humidity with respect to water) to RHi (relative humidity with respect to ice). https://www.metabunk.org/rh Currently it just takes RHw, temperature and pressure, and then gives you the RHi, and the value of RHw at which RHi is 100% (i.e...

    This is something I've been meaning to do for a while: a daily record of the contrails (or lack of contrails) in the sky, in a known location, compared to a daily record of the atmospheric conditions in that location, specifically the relative humidity at typical aircraft cruising height.
