The following table lists SMAP science data products and related data available from the NSIDC DAAC. The Level 1 products contain raw or calibrated and geolocated instrument measurements from the SMAP Radar and Radiometer; all Level 1 products have a temporal resolution of 49 minutes, the length of time required for the SMAP satellite to complete a half orbit of the Earth. The Level 2 products contain soil moisture retrievals derived from Level 1 products and ancillary files; all Level 2 products are based on half orbits, with a temporal resolution of 49 minutes. The Level 3 products are daily composites of the Level 2 soil moisture and freeze/thaw state data. The Level 4 products provide model-derived root-zone soil moisture and carbon net ecosystem exchange.
