MODIS/Aqua Snow Cover Daily L3 Global 500m Grid (MYD10A1) 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. MYD10A1 consists of 1200 km by 1200 km tiles of 500 m resolution data gridded in a sinusoidal map projection. MODIS/Aqua V004 data extend from 04 July 2002 to present. A sample of MODIS/Aqua V003 data from 29 August 2002 (day 241) through 07 October 2002 (day 280) allows users to correlate between V003 and later versions. This collection also includes several granules that were not reprocessed into V004. 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.

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.
