MOD10_L2 / MYD10_L2 snow products

These products are generated using the MODIS calibrated radiance data products (MOD02HKM and MYD02HKM), the geolocation products (MOD03 and MYD03), and the cloud mask products (MOD35_L2 and MYD35_L2) as inputs. The MODIS snow algorithm output (MOD10_L2 and MYD10_L2) contains scientific data sets (SDS) of snow cover, quality assurance (QA) SDSs, latitude and longitude SDSs, local attributes and global attributes. The snow cover algorithm identifies snow-covered land; it also identifies snow-covered ice on inland water. For complete global coverage a MOD10_L2 (or MYD10_L2) snow product would be generated for all swaths (approximately 288 swaths) of Terra or Aqua orbits acquired in daylight on the Earth. The Terra product, MOD10_L2, is validated (stage 2); the Aqua product, MYD10_L2, is provisional. See the validation webpage for further details and validation definitions.
