高亚洲逐日积雪覆盖度数据集（2002-2018年）

高亚洲是以青藏高原为主要区域的亚洲高海拔地区，是中低纬度高山积雪的重要分布区，其积雪的动态变化对水和能量平衡及区域气候具有重要的影响。由于青藏高原地区季节性积雪具有赋存时间短、雪层较薄的特点，在对水循环等问题的理解中，迫切需要日时间尺度的积雪覆盖度动态监测数据。本数据集基于空间分辨率...

High Asia refers to the high-altitude regions of Asia primarily centered on the Qinghai-Tibet Plateau, which is an important distribution area of mountain snow cover at mid-to-low latitudes. The dynamic changes of its snow cover exert significant impacts on water and energy balance as well as regional climate. Given that seasonal snow cover on the Qinghai-Tibet Plateau features short occurrence duration and thin snow layer, there is an urgent demand for dynamic monitoring data of snow cover fraction at daily time scales to advance the understanding of issues such as the water cycle. This dataset is based on spatial resolution...
