MODIS/Terra Snow Cover Daily L3 Global 500m Grid (MOD10A1) contains snow cover and quality assurance (QA) data in HDF-EOS format along with corresponding metadata. Data files after 14 September 2003 include a snow albedo array with a beta status. MOD10A1 consists of 1200 km by 1200 km tiles of 500 m resolution data gridded in a sinusoidal map projection. MODIS/Terra V004 data extend from 24 February 2000 to present. MODIS snow cover data are based on a snow mapping algorithm that employs a Normalized Difference Snow Index (NDSI) and other criteria tests. Data are available via FTP, CD-ROM, DLT, or DVD.

Please note that NSIDC now has a complete series of Version 5 data, which is the highest version number now available and represents the best quality of data.
