SPECTRORADIOMETERS

The MODIS/Terra Snow Cover Daily L3 Global 500m Grid (MOD10A1) contains snow cover, snow albedo, fractional snow cover, and Quality Assessment (QA) data in compressed Hierarchical Data Format-Earth Observing System (HDF-EOS) format along with corresponding metadata. MOD10A1 consists of 1200 km by 1200 km tiles of 500 m resolution data gridded in a sinusoidal map projection. The Moderate Resolution Imaging Spectroradiometer (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 Version 5 (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.
