SMAP L2 Radar/Radiometer Half-Orbit 9 km EASE-Grid Soil Moisture V003

Published by NASA NSIDC DAAC | National Aeronautics and Space Administration | Catalog Last Checked: August 04, 2025 at 02:23 PM | Dataset Last Updated: March 31, 2025
This Level-2 (L2) soil moisture product provides estimates of global land surface conditions retrieved by both the Soil Moisture Active Passive (SMAP) radar and radiometer during 6:00 a.m. descending half-orbit passes. SMAP L-band backscatter and brightness temperatures are used to derive soil moisture data, which are then resampled to an Earth-fixed, global, cylindrical 9 km Equal-Area Scalable Earth Grid, Version 2.0 (EASE-Grid 2.0).
