The polarization index (PI) of special sensor microwave/imager (SSM/I) radiance is derived from a radiative transfer equation and applied to identifying spatial and temporal variations of terrain surface moisture. The index PI, its deviation from the multiyear monthly average , Δ n PI, and a scattering index SI are utilized to monitor flooding of the Huaihe River, China, in July 2003. An anomaly index K, based on statistics of the indices PI and SI, is defined to quantitatively evaluate the flooding situation over vast areas.
