| Abstract | Question: Previous studies by some researchers suggest that microwave data with frequencies higher than I0 GHz are not appropriate for soil moisture estimation since the vegetation will strongly mask out most surface information at these high frequencies. However, in a recent study, Calvet et al. indicated that the top surface soil moisture can be retrieved with acceptable accuracy at higher microwave frequencies with a theoretical model if vegetation coverage is less than 50% of the area or if vegetation such as agricultural crops are at an early stage of growth. This study addresses whether 19 GHz SSM/I data over a grassland region can be used to retrieve surface soil moisture accurately. |
