SMAP L2 Radar Half-Orbit 3 km EASE-Grid Soil Moisture V003

Published by NASA NSIDC DAAC | National Aeronautics and Space Administration | Metadata Last Checked: August 04, 2025 | Last Modified: 2025-03-31
This Level-2 (L2) soil moisture product provides estimates of global land surface conditions retrieved by the Soil Moisture Active Passive (SMAP) active radar during 6:00 a.m. descending half-orbit passes, as well as ancillary data such as surface temperature and vegetation water content. Input backscatter data used to derive soil moisture are resampled to an Earth-fixed, global, cylindrical 3 km Equal-Area Scalable Earth Grid, Version 2.0 (EASE-Grid 2.0).
