M. Shoshany et al., The relationship between ERS-2 SAR backscatter and soil moisture: generalization from a humid to semi-arid transect, INT J REMOT, 21(11), 2000, pp. 2337-2343
A linear relationship between ERS-2 SAR backscattering coefficient (sigma(0
)) and volumetric soil moisture was determined at both ends of a rainfall g
radient in Israel. A Normalized radar Blackscatter soil Moisture Index (NBM
I) was derived and related strongly to soil moisture concentration. This in
dex may allow the mapping of soil moisture conditions over large areas with
C band SAR data.
