A New Approach for Retrieving Surface Soil Moisture and Vegetation Parameters
並列摘要
A new approach for retrieving surface soil moisture and vegetation parameters based on multi-angular L-band brightness temperature data is presented in this paper. Relationships of soil emissivity at different incidence angles are derived using Advanced Integral Equation Model simulated database, and a linear function for brightness temperatures with two incidence angles is derived, in which the intercept and slope depend only on vegetation properties. Soil moisture can be retrieved using dual-polarization observations after surface roughness corrections based on a parameterized surface emission model. Validation using soil moisture networks indicates that this approach performs well in surface soil moisture retrieval. Retrieved soil moisture agrees well with in situ measurements with the rmse close to 0.04 m^3/m^3.
