Abstract

A multifrequency passive microwave remote sensing system was deployed during a ground-based experiment. Conducted near Huntsville, Alabama in 1996. The Sand L-band microwave radiometers were able to detect both the large scale moisture changes due to the irrigation and rainfall events and also diurnal fluctuations in surface soil moisture content. Using a two frequency system provides much more information about near-surface soil water dynamics than does a single frequency
