Raindrop temperature model

Surface observations include surface temperature, dew point temperature, wet-bulb 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 when freezing rain occurred. 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. The borderline_precip include the sounding profiles of the rain and freezing rain events when the surface temperature near 0℃(-1~1℃).

本数据集涵盖了自2000年1月至2019年12月期间，在00:00、06:00、12:00及18:00 UTC时，由2168个地面观测站提供的地表温度、露点温度、湿球温度以及天气现象数据。此外，针对结冰雨事件，从中国境内89个观测站收集到的探空剖面数据，这些数据可在雨滴温度模型中直接应用，以计算雨滴从云底降落时的温度。边界降水数据包括近0℃（-1至1℃）地表温度时，降雨和结冰雨事件的探空剖面。
