Description
Surface temperature and radiation data were collected at two sites in the FIFE study area during July and August 1989. The dataset contains hemispherical surface temperature, temperatures measured at multiple view zenith angles, and azimuth increments of 45 degrees, collected using Everest and Eppley infrared radiometers. Its purpose was to characterize bi-directional reflectance, estimate surface albedo, and analyze flux variability as a function of topography, vegetation, and plant water status.
Use Cases
Characterizing bi-directional reflectance factor distributions from multi-angle temperature measurements.
Estimating surface albedo using bi-directional reflectance factor and radiance data.
Analyzing variability of reflected and emitted radiation fluxes across different topographic and vegetative conditions.
Investigating the influence of plant water status on surface reflectance factors.
Determining sun angle effects on surface radiation fluxes.
Strengths
Data collected using specific, documented instruments (Everest IRT Model 4000, Eppley PIR).
Includes periodic measurements of surface emissivity and incoming longwave radiation.
Provides multi-angle surface temperature measurements at specific view zenith and 45-degree azimuth increments.
Limitations
Column names and exact row count are unknown, limiting precise data understanding.
