SAMPLE_DESCRIPTION:
Averaged spectral reflectance for an area dominated by big sagebrush located in the Gardner River area (north of Mammoth Hot Springs) of Yellowstone National Park. The majority of the sagebrush shrubs in this area were observed to be greater than 1.0 meter in height. This area was described by Despain (1990) as big sagebrush/Idaho fescue habitat. This average spectrum was computed from 81 pixels of radiative-transfer-ground-calibrated AVIRIS data. AVIRIS data were collected on August 6, 1996, at approximately 11:10 am Local Time. AVIRIS channels 1-4, 32-33, 43, 59-62, 81-84, 95-97, 106-113, 154-167, 173-175, and 222-224 were deleted due to residual atmospheric effects, poor instrument response, and redundancy where detectors overlap.
