西南山地天气现象实况数据集

本数据集专注于构建高时空分辨率的西南山地天气现象观测数据库，系统性地整合降水相态、强对流天气、视程障碍及地面凝结现象等关键气象要素，并融合地形高程、坡向坡度等地理信息。包含近3年的时间分辨率为逐日，水平空间分辨率为5km×5km的网格化雨、雪、雨夹雪、冻雨等降水相态；雷暴等强对流天气；雾等视程障碍；结冰等地面现象。

This dataset focuses on constructing an observational database of weather phenomena in the mountainous regions of Southwest China with high spatiotemporal resolution. It systematically integrates key meteorological elements including precipitation phases, severe convective weather, visibility-impeding obstacles and surface condensation phenomena, and incorporates geographic information such as terrain elevation, slope aspect and slope gradient. The dataset covers data from the last three years, with a daily temporal resolution and a horizontal spatial resolution of 5 km × 5 km, including gridded precipitation phases such as rain, snow, sleet and freezing rain; severe convective weather events like thunderstorms; visibility-affecting phenomena such as fog; and surface phenomena such as icing.
