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

Low altitude (Ultralight) spectral reflectances of OTTER research sites measured by Spectron SE590 spectrophotometer.

timber_125

Height, crown width, DBH, and height-to-crown distance collected using variable-radius plot sampling with a steel tape and a hand held compass to locate points along a transect.
