中国逐日500m雪水当量产品（1980-2020年）

雪水当量（SWE）是评价雪水文、气候调节和水资源管理的关键参数。针对中国积雪分布区，基于多源遥感数据融合与机器学习降尺度技术，综合考虑积雪范围、地形和地理位置等影响积雪分布的环境因子，发展精细化雪水当量降尺度模型，制备1980-2020年逐日500m雪水当量数据集。利用地面观测站点数...

Snow Water Equivalent (SWE) is a critical parameter for evaluating snow hydrology, climate regulation and water resources management. For snow-covered regions in China, a refined downscaling model for snow water equivalent was developed based on multi-source remote sensing data fusion and machine learning downscaling techniques, comprehensively considering environmental factors affecting snow distribution such as snow cover extent, topography and geographic location. A daily 500m snow water equivalent dataset spanning from 1980 to 2020 was produced. Ground observation station data was utilized for...
