ER2 EARTH AVIRIS CALIBRATED REDUCED DATA RECORD IMAGE V1.0

More than 40 scenes were generated during GRSFE, more than 20 of which are included on the CD-ROMs, covering a variety of surfaces. Lunar Crater was covered several times in one day (under clear atmospheric conditions) in order to evaluate atmospheric scattering and absorption removal algorithms and to explore extraction of roughness information using variable incidence angle AVIRIS data.

The AVIRIS multi-temporal data were acquired at the same time that ground-based, multi-spectral measurements of atmospheric optical depth, and sky radiance at varying scattering angles were acquired, along with surface bidirectional reflectance data. Accurate wavelength calibration of AVIRIS was performed by JPL using laboratory measurements acquired before and after the AVIRIS flights. An additional check on the wavelength calibration can be made by comparing the positions of known atmospheric absorption features to their locations in actual AVIRIS data.
