MYD10A1.006 Aqua Snow Cover Daily Global 500m (MODIS/006/MYD10A1)

Version V006

The MYD10A1 V6 Snow Cover Daily Global 500m product contains snow cover, snow albedo, fractional snow cover, and quality assessment (QA) data. Snow cover data are based on a snow mapping algorithm that employs a Normalized Difference Snow Index (NDSI) and other criteria tests.

NameDescription
NDSI_Snow_CoverNDSI snow cover. This value is computed for MOD10_L2 and retrieved when the observation of the day is selected. Provider values above 100 are masked out in this band (they can be found in the "NDSI_Snow_Cover_Class" band).
NDSI_Snow_Cover_Basic_QAA basic estimate of the quality of the algorithm result. This value is computed for MOD10_L2 and retrieved with the corresponding observation of the day.
NDSI_Snow_Cover_Algorithm_Flags_QABit flags indicating screen results and the presence of inland water. These flags are set when MOD10_L2 is generated and retrieved with the corresponding observation of the day.
NDSIRaw NDSI (i.e. prior to screening). This value is computed for MOD10_L2 and retrieved with the corresponding observation of the day.
Snow_Albedo_Daily_TileSnow albedo percentage. Provider values above 100 are masked out in this band (they can be found in the "Snow_Albedo_Daily_Tile_Class" band).'
orbit_pntPointer to the orbit number of the swath that was selected as the observation of the day. The pointer references by index the list of orbit numbers written to the ORBITNUMBERARRAY metadata object in ArchiveMetadata.0.
granule_pntPointer to the granule (swath) that was mapped into the tile. The pointer references the corresponding value in the GRANULEPOINTERARRAY metadata object written to ArchiveMetadata.0.
NDSI_Snow_Cover_ClassLandcover classes from the "NDSI_Snow_Cover" subdataset (provider values less than or equal to 100 are masked out).
Snow_Albedo_Daily_Tile_ClassLandcover classes from the "Snow_Albedo_Daily_Tile" subdataset (provider values less than or equal to 100 are masked out).
