A Validation Method for Bare Soil Surface Parameters Inverted by Oh Empirical Model Using Integral Equation Method

摘要：

A new method is developed to validate the parameter inversion results of the empirical models proposed by Oh et al. for bare soil surface. Oh et al. developed a series of empirical models for retrieving bare soil moisture and root mean square (rms) height, while Fung et al. proposed Integral Equation Method (IEM) to provide the relationship between backscattering coefficient and surface parameters in a rather wide range of roughness and moisture conditions. The proposed validation method combines the empirical scattering model Oh and the theoretical scattering model IEM, which provides a method to show the accuracy of the inversion results. This method needs no ground truth measurement of surface in situ.
