Abstract :
Brightness temperatures from NOAA-18 and NOAA-19 MHS measurements are investigated over Antarctica to establish it as a natural vicarious calibration target for determination of the Inter-satellite/inter-sensor Calibration Biases (ICB) of the two MHS radiometers. Establishment of a natural test site for calibration references is important for calibration and validation of space-borne microwave instruments.
