资源简介：
This data set contains daily 'cloud-free' snow cover produced from the VIIRS/JPSS-1 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....
本数据集包含基于VIIRS/JPSS-1每日积雪覆盖L3级全球375米正弦网格（SIN Grid）V2版积雪产品生成的每日“无云”积雪覆盖数据。本数据集采用云间隙填充算法，将“被云覆盖”的像素替换为“无云像素”，以估算当前云层下可能存在的积雪覆盖情况。该数据按每日频次提供，并投影至375米正弦网格中……
