SMAP Level-4 data sets, accessible through the NASA National Snow and Ice Data Center Distributed Active Archive Center (NSIDC DAAC), can now be subsetted for a spatial area defined by a shapefile, KML/KMZ, or GeoJSON. This service can be invoked via NASA Earthdata Search or via programmatic access.
The following help articles describe all the customization services currently available for these SMAP data sets and give instructions on data access through NASA Earthdata Search or programmatically:
- What data subsetting, reformatting, and reprojection services are available for SMAP data?
- Search, order, and customize NSIDC DAAC data with NASA Earthdata Search
