Data Set:
SMAP/CYGNSS EASE-Grid Soil Moisture, Version 1
Data Set ID:
NSIDC-0797
Data Set Summary:
This data set is derived by downscaling Soil Moisture Active Passive (SMAP) enhanced Level-3 9 km brightness temperatures (TB) using Cyclone Global Navigation Satellite System (CYGNSS) reflectivity data and employing a slightly modified version of the SMAP baseline active-passive TB algorithm. The SMAP Single Channel Algorithm – Vertical polarization (SCA-V) is then used to derive soil moisture from SMAP/CYGNSS Tb data. The main parameter of this data set is surface soil moisture presented on the Global EASE-Grid 2.0 projection, with each data point representing the top 5 cm of the soil column. For SMAP-derived data, see SMAP Enhanced L3 Radiometer Global and Polar Grid Daily 9 km EASE-Grid Soil Moisture, Version 5; for CYGNSS-derived data, see CYGNSS Level 1, Version 2.1.
