In-flight refinement of the radiometric, spectral, and spatial calibration of the Atmospheric Infrared Sounder (AIRS)

The current performance of AIRS radiometric, spectral, and spatial calibration algorithms are described. Radiometric accuracy is validated to tenths of a kelvin. Spectral stability is better than 0.5% of the spectral response function FWHM. Geolocation accuracy is accurate to approximately 2 km at nadir. An algorithm has been implemented to correct for space views contaminated by the moon. Planned algorithm improvements include correcting the 2 km bias in geolocation.
