MODIS/Aqua Snow Cover Daily L3 Global 0.05Deg CMG, Version 5

The MODIS/Aqua Snow Cover Daily L3 Global 0.05Deg CMG (MYD10C1) data set contains snow cover and Quality Assessment (QA) data, latitudes and longitudes in compressed Hierarchical Data Format-Earth Observing System (HDF-EOS) format, and corresponding metadata. This data set consists of 7200 columns by 3600 rows of global arrays of snow cover in a 0.05 degree Climate Modeling Grid (CMG). MODIS snow cover data are based on a snow mapping algorithm that employs a Normalized Difference Snow Index (NDSI) and other criteria tests.MODIS/Aqua积雪每日全球三级0.05度气候建模网格（Climate Modeling Grid, CMG）数据集（MYD10C1）包含积雪数据、质量评估（Quality Assessment, QA）数据与经纬度数据，所有数据均以压缩分层数据格式-地球观测系统（Hierarchical Data Format-Earth Observing System, HDF-EOS）格式存储，并附带对应元数据。该数据集基于0.05度气候建模网格构建，包含尺寸为7200列×3600行的全球积雪阵列。MODIS积雪数据基于采用归一化积雪指数（Normalized Difference Snow Index, NDSI）及其他判定准则的积雪制图算法生成。
