Abstract
The Atmospheric Infrared Sounder (AIRS) was launched on May 4, 2002 on the NASA Aqua Satellite. AIRS measures the infrared spectrum in 2378 channels with a very high spectral resolution of approximately 1200. In this paper, the spatial properties of the infrared channels are presented in their flight configuration. The spatial response for any single channel is slightly irregular and rotates off nadir due to image rotation in the scan mirror. AIRS has several channels with the same spectral frequencies but different spatial responses. These channels are used to demonstrate the efficacy of resampling using standard techniques to improve the co-registration
