HgCdTe Detector Responsivity and GOES Instrument Calibration

Abstract : A model is developed for the responsivity of HgCdTe detectors employed in the GOES Sounder and Imager instruments. Response non-linearity is related to the calibrated radiometric accuracy of the instruments. The model, in the form of a computer code, could be utilized to expedite pre-launch calibration of GOES satellite instruments and to provide confidence in GOES in-orbit calibration procedures.
