SMAP L2 Radiometer Half-Orbit 36 km EASE-Grid Soil Moisture V002

This Level-2 (L2) soil moisture product provides gridded estimates of global land surface conditions retrieved by the Soil Moisture Active Passive (SMAP) passive microwave radiometer during 6:00 a.m. descending half-orbit passes. Input SMAP L-band brightness temperature data used to derive soil moisture are resampled to an Earth-fixed, global, cylindrical 36 km Equal-Area Scalable Earth Grid, Version 2.0 (EASE-Grid 2.0). A variety of ancillary data are also used as input, such as soil texture and vegetation opacity. Note: These data are Beta-release quality, meaning that they have not undergone full validation and may still contain significant errors.
