Abstract

The Microwave Humidity Sounders (MHS) on NOAA and Metop satellites have been extensively inter-satellite cross-calibrated; thus these MHS radiometers serve as the radiometric calibration standards for other satellite sounder radiometers. Unfortunately, inter-satellite radiometric calibration (aka XCAL) between similar, but not identical, radiometers is not trivial. This paper explores the application of a 'Double-Difference (DD)' XCAL technique to sounders, which has been successfully used for conical scanning microwave imagers. Specifically, the water vapor sounder Sondeur Atmosphérique du Profil d'Humidité Intertropicale par Radiométrie (SAPHIR) on the Megha-Tropiques satellite is inter-satellite calibrated using the MHS instruments on the NOAA-18, NOAA-19, and Metop-A satellites.
