IMAGING SPECTROSCOPY AND THE AIRBORNE VISIBLE INFRARED IMAGING SPECTROMETER (AVIRIS)

Imaging spectroscopy is of growing interest as a new approach to Earth remote sensing. The Airborne Visible/Infrared Imaging Spectrometer (A VIRIS) was the first imaging sensor to measure the solar reflected spe ctrum from 400 nm to 2500 nm at 10 nm intervals. The calibration accur acy and signal-to-noise of AVIRIS remain unique. The AVIRIS system as well as the science research and applications have evolved significant ly in recent years. The initial design and upgraded characteristics of the AVIRIS system are described in terms of the sensor, calibration, data system, and flight operation. This update on the characteristics of AVIRIS provides the context for the science research and applicatio ns that use AVIRIS data acquired in the past several years. Recent sci ence research and applications are reviewed spanning investigations of atmospheric correction, ecology and vegetation, geology and soils, in land and coastal waters, the atmosphere, snow and ice hydrology, bioma ss burning, environmental hazards, satellite simulation and calibratio n commercial applications, spectral algorithms, human infrastructure, as well as spectral modeling.
