Abstract	On November 21, 2000, NASA launched the EO-1 satellite, carrying the Hyperion hyperspectral imager, into an orbit precisely following LANDSAT-7 by 1 minute. Hyperion has a 7.5 km swath width, a 30 meter ground resolution and 220 spectral bands. Its spectral bands extend from 400 nm to 2500 nm with each band having about a 10 nm bandwidth. A unique process to validate the spectral calibration that is based on an the atmospheric limb data collect has been developed. The data contained a collection of solar lines, atmospheric lines and absorption lines from the paint which coats the solar calibration reflectance panel. Correlating the positions of these lines with reference data, the center wavelength of each pixel across the field of view for the SWIR spectral regions of the imaging spectrometer has been verified. In this paper we discuss the data collection and the technique applied to the SWIR focal plane array.
