A physically-based inversion algorithm for retrieving soil moisture in passive microwave remote sensing

► By reducing degrees of freedom of the Fresnel equation, a unique inversion algorithm (Hong’s algorithm) is developed for retrieving soil moisture in passive microwave remote sensing. ► The surface roughness and the dielectric constant are retrieved using Hong’s approximation. ► The Hong’s algorith...
