Paper Abstract

The Hyperspectral Data and Information Collection Experiment (HYDICE) collected data during 1995 for purposes of assessing and verifying performance. Accurate wavelength calibration to +/- 0.1 nm is essential for proper application of atmospheric models in order to derive apparent surface reflectance. A method for precise wavelength calibration is described that makes use of the narrow atmospheric oxygen band absorption feature at 762 nm. Precision of +/- 0.1 nm is feasible despite variable surface cover if the signal-to-noise ratio is greater than 100. Resampling the HYDICE images to a common wavelength results in reduced spectral resolution and adversely affects the radiometric accuracy of narrow features such as the oxygen band.
