The MODIS/Aqua Snow Cover Monthly L3 Global 0.05Deg CMG (MYD10CM) data set, new for Version 5 (V005), contains snow cover and Quality Assessment (QA) data in Hierarchical Data Format- Earth Observing System (HDF-EOS) format, and corresponding metadata. This data set consists of 7200 column by 3600 row global arrays of snow cover in a 0.05 deg 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. Monthly average snow cover is calculated from the daily global products for the month. MODIS/Aqua V005 data extend from 24 February 2000 to present; however, until reprocessing is complete in mid-2008 not all V005 data will be available. Data are available via FTP, CD-ROM, DLT, or DVD. Data can be obtained in GeoTIFF format by ordering the data through the Data Pool.

Until the reprocessing campaign is finished, the complete set of Version 4 (V004) data will remain available. Thus, if you need V004 documentation, please contact the National Snow and Ice Data Center (NSIDC) User Services at http://nsidc.org/forms/contact.html.
