This global Level-3 data set (MYD10A1F) provides daily cloud-free snow cover derived from the MODIS/Aqua Snow Cover Daily L3 Global 500m SIN Grid data set (MYD10A1). Grid cells in MYD10A1 which are obscured by cloud cover are filled by retaining clear-sky views of the surface from previous days. A separate parameter is provided which tracks the number of days in each cell since the last clear-sky observation. Each data granule contains a 10° x 10° tile projected to the 500 m sinusoidal grid. The terms "Version 61" and "Collection 6.1" are used interchangeably in reference t...本全球三级数据集（Level-3 data set）MYD10A1F，源自中分辨率成像光谱辐射计/Aqua卫星（MODIS/Aqua）的《每日全球500米正弦网格（SIN Grid）雪覆盖三级数据集（MYD10A1）》，可提供每日无云积雪覆盖数据产品。MYD10A1中被云层遮蔽的网格单元，将通过复用前期地表晴空观测数据完成填充。数据集还配备了一项独立参数，用于追踪每个网格单元自末次晴空观测以来的间隔天数。每个数据分块（data granule）均包含一个投影至500米正弦网格的10°×10°瓦片。“版本61”与“合集6.1”在指代相关内容时可互换使用……
