spectra_perkin_48
Absolute reflectance of leaves measured in the lab by Perkin-Elmer spectrophotometer to aid in understanding remotely sensed spectral data.
meteo_50
Meteorology data collected on an hourly basis from stations located near the OTTER sites in 1990 and summarized to monthly data.
airsunp_61
Airborne sun photometer data collected from 1990 through 1991 used to provide quantitative atmospheric correction to remotely sensed data of forest reflectance and radiance.
fieldsunp_65
Field sun photometer data collected from 1990 through 1991 is used to provide quantitative atmospheric correction to remotely sensed data of forest reflectance and radiance.
spectra_target_74
Spectral reflectance measurements of flat field targets as reference points representative of psuedo-invariant targets as measured by the Spectron SE590 spectrophotometer.
spectra_se590_field_80
Spectral reflectance measurements made by Spectron SE590 instruments in the context of validation of geometric-optical BRDF models.
spectra_se590_lab_83
Laboratory hemispherical reflectance spectra measurements taken to eliminate the effects of atmosphere, understory, exposed soils, mixed species and canopy architecture.
spectra_se590_landscape_84
Bidirectional spectral reflectance factors of landscape elements (litter, scrubs and grasses, leaves) measured by the Spectron SE590 spectroradiometer.
spectra_se590_altitude_86
