Abstract :
The ability to estimate soil moisture in the surface layer by microwave remote sensing has been demonstrated. But its application to hydrological and agricultural sciences has been hampered by the complexity of the vegetation canopy and surface roughness which significantly affect the sensitivity of radar backscattering to soil moisture. In this study, we used a simple vegetation model to estimate soil moisture and evaluated the results using multi-temporal L-band AirSAR data
