Technical Abstract: Heterogeneity is one of the critical issues of passive microwave remote sensing of land surface hydrological parameters such as soil moisture, surface temperature, and water content. Due to the large foot print size of spaceborne and aircraft sensors, ground-based instruments can contribute to understanding the effects of land surface heterogeneity and to algorithm validation. There are few data sets of the diurnal cycle that have been observed by microwave radiometers. A ground-based microwave radiometer (GBMR) was deployed in the SGP99 to address these issues. The three frequency radiometer was used to collect data for a number of experimental designs. Preliminary results suggest strong near surface profile effects on the response at these frequencies.
