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

The MODIS/Terra Snow Cover Daily L3 Global 0.05Deg CMG (MOD10C1) 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/Terra每日积雪覆盖L3级全球0.05度气候建模网格（Climate Modeling Grid，CMG）数据集（MOD10C1）包含积雪覆盖与质量评估（Quality Assessment，QA）数据、以压缩分层数据格式-地球观测系统（Hierarchical Data Format-Earth Observing System，HDF-EOS）格式存储的经纬度数据，以及配套元数据。该数据集由7200列×3600行的0.05度气候建模网格全球积雪覆盖阵列构成。MODIS积雪覆盖数据基于采用归一化积雪指数（Normalized Difference Snow Index，NDSI）与其他判定准则的积雪制图算法。
