Abstract

This paper describes the equipment used to radiometrically calibrate the Earth Radiation Budget Experiment (ERBE) space-borne instrument complement in a thermal vacuum chamber. The ERBE instruments will monitor on a global, continuous, basis the incoming solar irradiance of the earth albedo, the earth's thermal emission, and the spatial and directional characteristics of the earth's thermal emission and albedo. The calibration equipment described in this paper consists of a master reference black-body source, a short wavelength calibration integrating sphere, an albedo simulator plate, and a space reference source. The design and performance characteristics of each of these sources, as well as the techniques used to provide a radiometric environment for the ERBE instruments equivalent to that of the orbit, are also discussed. Analytical and measured performance parameters of these sources are also described.
