A linear relationship between ERS-2 SAR backscattering coefficient (sigma(0)) and volumetric soil moisture was determined at both ends of a rainfall gradient in Israel. A Normalized radar Blackscatter soil Moisture Index (NBMI) was derived and related strongly to soil moisture concentration. This index may allow the mapping of soil moisture conditions over large areas with C band SAR data.
