Retrieval of soil moisture using electromagnetic models and a Bayesian approach in view of the SAOCOM mission: Study on SARAT images in an agricultural site in Argentina

The aim of this research is to examine the ability of an approach based on Bayesian inference to retrieve surface soil moisture in an experimental agricultural area located in the province of Córdoba, Argentina. Radar images from SARAT sensor were used, as well as measurements of biophysical paramet...
