Abstract

The in-flight radiometric stability of images formed in a single spectral band of HYDICE has been examined under various conditions. In the first, the stability of the combined response of the on-board calibrator and HYDICE was checked by comparing repeated image acquisitions over small targets, a few pixels in size, and then over a uniform, extended target. For the second condition, a new flat-field calibration of the focal plane was used which improved the radiometric stability. It is shown from these results that radiometric stability and accuracy are closely related to target contrast and size. This has important consequences for the empirical line approach to calibration or reflectance retrieval. The third condition included a pitch in the attitude of the aircraft that introduced a marked banding of the image in the vicinity of the 1.38-micrometers band, which is very sensitive to the presence of cirrus-cloud ice crystals. This is believed to be another form of the `spectral jitter' described in other papers in these Proceedings.
