The Microwave Airborne Radiometer Scanning System (MARSS) is a passive, along-track scanning microwave radiometer developed by the United Kingdom Met Office and Laboratoire de Méteórologie Dynamique du Centre National de Recherche Scientifique (LMD CNRS). It measures brightness temperature across five channels, including two at 89 and 157 GHz and three centered on the water vapor absorption line at 183 GHz. It is typically used for the calibration and validation of satellite observations. MARSS has a 3-second scan time and an accuracy of better than 1 K.
