Abstract

Nimbus/SMMR data have been used together with an extensive data base of soil moisture (1984-1987) to study the potential for large scale surface moisture monitoring. In order to study the influences of vegetation on the signals gathered from space, a radiative transfer model has been used to simulate the below canopy emissivity. Vegetation characteristics were subsequently estimated from inverse modeling and related to NDVI (synergistic approach) and to H- and V-polarization signatures (dual-polarization approach). Results of both approaches will be presented and compared. In order to validate the dual-polarization concept, which was applied to account for the radiative transfer properties of the vegetation, field measurements of single scattering albedo and optical depth were carried out recently for an agricultural crop.
