VIIRS/NPP CGF Snow Cover Daily L3 Global 375m SIN Grid, Version 2

This data set contains daily 'cloud-free' snow cover produced from the VIIRS/NPP 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/NPP每日积雪覆盖L3全球375米正弦网格（SIN Grid，版本2）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”，以估算当前云层覆盖下可能存在的积雪覆盖情况。该数据每日更新，并映射至375米正弦网格。
