Abstract :
In this paper the development of a semi-empirical algorithm for estimating soil moisture content from dual-frequency (C- and X-bands) microwave AMSR data is demonstrated. The algorithm is based on a simplifies form of the radiative transfer theory and computes the optical depth through the polarization index at X-band. Validation of the algorithm was attempted first with SMMR data collected in Russia in 1979-1981.
