Sample Description
Averaged spectral reflectance for a grassland area, dominated by Idaho fescue and bearded wheatgrass, located on Specimen ridge (south side of the Lamar Valley) of Yellowstone National Park. This area was described by Despain (1990) as the wet phase (containing sticky geranium, Geranium viscosissimum) of the Idaho fescue/bearded wheatgrass habitat. This average spectrum was computed from 62 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.
