The Snow Water Equivalent Synthetic Aperture Radar and Radiometer (SWESARR) is an airborne remote sensor developed at NASA’s Goddard Space Flight Center (GSFC). It comprises a synthetic aperture radar (SAR) and a microwave radiometer for snow water equivalent (SWE) retrievals. The SAR measures radar backscatter at 9.65, 13.6, and 17.25 GHz. It has a nominal range resolution of 1.1 m and a swath width of 250 to 450 m, depending on the operating frequency. The radiometer measures brightness temperature at 10.65, 18.7, and 36.5 GHz. At a nominal altitude of 1500 m, it has spatial resolutions of 496 x 353 m, 282 x 200 m, and 144 x 102 m for the X-band, K-band, and Ka-band, respectively.
