MEASURING SOIL MOISTURE WITH AN AIRBORNE IMAGING PASSIVE MICROWAVE RADIOMETER

Short of exhaustive field sampling, no dependable method for gathering regional soil moisture data presently exists. Passive microwave remote sensing technology has the ability to provide areally extensive information on near-surface soil moisture condition. Experiments conducted with an imaging passive microwave radiometer on the West Side, San Joaquin Valley, California, indicate that a statistically highly significant linear correlation exists between image tone density and moisture content in the top 5 cm of the soil. Further, this relationship may be seen to intensify somewhat when soils are subdivided by type and show a slightly stronger correlation for the less coarse of the two soil types present. /Author/
