Soil Moisture Active Passive (SMAP) L1-L3 Ancillary Static Data V001

Published by NASA NSIDC DAAC | National Aeronautics and Space Administration | Catalog Last Checked: February 14, 2026 at 08:24 PM | Dataset Last Updated: March 31, 2025
This ancillary SMAP product contains more than 50 data sets. These data sets contain the inputs necessary to create SMAP products from raw instrument counts, such as permanent masks (land, water, forest, urban, mountain, etc.), the grid cell average elevation and slope derived from a Digital Elevation Model (DEM), permanent open water fraction, soils information (primarily sand and clay fraction), vegetation parameters, and surface roughness parameters.
