WISM
Wideband Instrument for Snow Measurements

The Wideband Instrument for Snow Measurements (WISM) instrument was developed to address a remote sensing need to measure surface snowfall and its associated snow water equivalent. WISM consists of two airborne instruments: a dual-frequency (X and Ku) Synthetic Aperture Radar and a dual-frequency (X and Ka) radiometer with a shared common antenna aperture between the two.
