Raindrop temperature 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.本数据集的地面观测部分，包含2000年1月至2019年12月期间，全球2168个地面气象站在协调世界时（UTC）00:00、06:00、12:00及18:00四个时次的观测数据，具体涵盖地面气温、露点温度以及天气现象三类资料。探空廓线数据部分，针对冻雨事件，采集自中国境内89个探空站在协调世界时00:00与12:00两个时次的观测结果；该数据集可直接作为雨滴温度模型的输入，用于计算雨滴从云底下落过程中的温度。
