SAMPLE_DESCRIPTION:
Averaged spectral reflectance for an area dominated by big sagebrush located in the Lamar Valley area of Yellowstone National Park. The grasses in this area were greener than in the areas of samples YNP-SS1 and YNP-SS2 because of the relatively higher elevation of this site. This area was described by Despain (1990) as big sagebrush/Idaho fescue habitat. This average spectrum was computed from 129 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.
