MODIS/Terra Snow Cover Daily L3 Global 500m SIN Grid, Version 61

This global Level-3 (L3) data set provides a daily composite of snow cover and albedo derived from the 'MODIS/Terra Snow Cover 5-Min L2 Swath 500m' data set (DOI:10.5067/MODIS/MOD10_L2.061). Each data granule is a 10°x10° tile projected to a 500 m sinusoidal grid. The terms \"Version 61\" and \"Collection 6.1\" are used interchangeably in reference to this release of MODIS data.本全球三级（Level-3，简称L3）数据集源自「MODIS/Terra积雪覆盖5分钟二级（Level-2）条带500米」数据集（数字对象标识符Digital Object Identifier，简称DOI：10.5067/MODIS/MOD10_L2.061），提供积雪覆盖范围与反照率的每日合成产品。每个数据分块均为10°×10°的瓦片，投影至500米分辨率的正弦投影网格。在指代本次发布的MODIS数据时，术语“Version 61”与“Collection 6.1”可互换使用。
