Description

Seasonal Mountain Snow (SMS) mask derived from MODIS MOD10A2 snow cover extent and GTOPO30 digital elevation model produced at 30 arcsecond spatial resolution.

Three datasets are provided: the Seasonal Mountain Snow mask (MODIS_mtnsnow_classes), a seasonal snow cover classification (MODIS_snow_classes), and cool-season cloud percentages (MODIS_clouds). The classification systems are as follows:

MODIS_snow_classes:

  • 0: Little-to-no snow
  • 1: Indeterminate due to clouds
  • 2: Ephemeral snow
  • 3: Seasonal snow

MODIS_mtnsnow_classes:

  • 0: Mountains with little-to-no snow
  • 1: Indeterminate due to clouds
  • 2: Mountains with ephemeral snow
  • 3: Mountains with seasonal snow

MODIS_clouds

  • 0: < 5% of clouds during the cool season (defined Oct.-Mar. for Northern Hemisphere and Apr.-Sep. for Southern Hemisphere)
  • 1: 5% cool-season days with cloud cover
  • 2: 10% cool-season days with cloud cover
  • 3: 20% cool-season days with cloud cover
  • 4: 30% cool-season days with cloud cover
  • 5: 40% cool-season days with cloud cover
  • 6: 50% cool-season days with cloud cover
