raindrop temperature calculating model

Surface observations include surface temperature, dew point temperature, and weather phenomenon data from 2168 surface stations at 00:00, 06:00, 12:00, and 18:00 UTC for the period January 2000 to December 2019. Sounding profile data were collected from 89 sounding stations across China at 00:00 and 12:00 UTC for freezing rain events, and can be directly driven by a raindrop temperature model to calculate the temperature of raindrops as they fall from the cloud base.
