—In the radiometric sensing of soil moisture through a forest canopy, knowledge of canopy attenuation is required. Active sensors have the potential of providing this information since the backscatter signals are more sensitive to forest structure. In this paper, a new radar technique is presented for estimating canopy attenuation. The technique employs(More)
—In this study, a first-order radiative transfer (RT) model is developed to more accurately account for vegetation canopy scattering by modifying the basic τ −ω model (the zero-order RT solution). In order to optimally utilize microwave ra-diometric data in soil moisture (SM) retrievals over vegetated landscapes, a quantitative understanding of the(More)
Retrieving soil moisture from microwave brightness temperatures in the presence of vegetation has been the subject of much research in the past. Most microwave soil moisture retrieval algorithms for sensing soil moisture through a vegetation canopy have been developed at L, S and C band microwave frequencies. They have been based on a zero-order solution to(More)
Soil moisture is recognized as an important component of the water, energy, and carbon cycles at the interface between the Earth's surface and atmosphere. Current baseline soil moisture retrieval algorithms for microwave space missions have been developed and validated historically only over grasslands, agricultural crops, and generally light to moderate(More)
