This data set contains daily 'cloud-free' snow cover produced from the VIIRS/JPSS-2 Snow Cover Daily L3 Global 375m SIN Grid, Version 2 snow cover product. A cloud-gap-filled algorithm is utilized to replace ‘cloud-covered’ pixels with ‘cloud-free pixels’ for the purpose of estimating the snow cover that may exist under current cloud cover. The data are provided daily and mapped to a 375 m sinusoidal grid....本数据集源自VIIRS/JPSS-2逐日积雪覆盖全球L3级375米正弦网格（SIN Grid）V2版本积雪产品，包含每日‘无云’积雪覆盖数据。研究采用云间隙填充算法，将‘被云覆盖’的像素替换为‘无云像素’，以估算当前云覆盖下可能存在的积雪覆盖情况。该数据为逐日数据，并被映射至375米正弦网格中。
