Abstract : This study presents the use of passive microwaves to classify and estimate the surface soil moisture in a semi-arid, mountainous region. The southwestern region of Saudi Arabia was chosen for this study. Two case studies have been considered to investigate the response of Special Sensor Microwave/Imager (SSM/I) brightness temperature to soil moisture. The first case is at satellite ascending overpass time (about 6:00 a.m. local solar time), and the second one is at satellite descending overpass time (about 6:00 p.m. local solar time). It is shown that normalized brightness temperature with respect to ground temperature may be interpreted in terms of the soil moisture in the surface layers. Normalized brightness temperature is not sensitive to soil moisture when precipitating clouds are present. The existence of precipitating clouds over the study area was determined through examination of the brightness temperature of frequency 85.5 GHz (Gigahertz).
