Testing semi-empirical model of reflection coefficient based on GNSSR measurements
2016
In this paper, with using of semi-empirical model of the reflection coefficient, which is implementing to calculate the brightness temperature of the SMOS spacecraft at 1.4GHz in [1], [2] the soil moisture was retrieved from the reflection coefficients, which were measured by GNSS-reflectometer at a test site on the Yamal Peninsula. The model of reflection coefficient with root-mean square error (RMSE) of 0.04 allows to predict the experimental values of the reflection coefficient and with RMSE of less than 0.09cm 3 /cm 3 allows to retrieve the soil moisture in the layer of 0–6cm.
