The UCAR/CU CYGNSS Soil Moisture Product
Listed in National Center for Atmospheric Research
This dataset provides soil moisture retrievals, which have been gridded to 36 km, for the upper 5 cm of the soil surface at sparsely-sampled 6-hour intervals for +/- 38 degrees latitude for 2017 - present.
Description
Retrievals are derived from the Cyclone Global Navigation Satellite System (CYGNSS) constellation, which uses GNSS-Reflectometry to obtain L-band surface reflectivity observations over the land and ocean surface. This product, the UCAR/CU CYGNSS Soil Moisture Product, was jointly developed by the University Corporation for Atmospheric Research and the University of Colorado Boulder.
It was developed by calibrating observations of surface reflectivity from CYGNSS to soil moisture retrievals from NASA's Soil Moisture Active Passive (SMAP) mission. Retrievals were validated against observations from over 200 in situ soil moisture probes from 5 networks, with an overall unbiased root mean square error (ubRMSE) of 0.047 cm3 cm-3.
