SMAP L2 Radar Half-Orbit 3 km EASE-Grid Soil Moisture, Version 2
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).
Note: These data are Beta-release quality, meaning that they have not undergone full validation and may still contain significant errors.
There is a more recent version of these data.
