Paper Abstract

The National Aeronautics and Space Administration's (NASA) Earth Radiation Budget Experiment (ERBE) measures the three radiant energy components (incident Solar, reflected, and emitted) of the Earth-Atmosphere System. This experiment employs four Earth-viewing nonscanning active cavity type radiometers on each the NASA Earth Radiation Budget Satellite (ERBS), and the National Oceanic and Atmospheric Administration's NOAA-9 and NOAA-10 spacecraft. The NOAA-9 and the NOAA-10 spacecraft are in Sun-synchronous polar orbits while the low-inclination orbit of the ERBS spacecraft precesses in local solar time. Two of the radiometers are total channels which measure radiation in the wavelength region of 0.2 to > 50 micrometers, while the other two radiometers are shortwave channels which measure the solar reflected energy in the spectral band of 0.2 to < 5 micrometers. A validation technique based on normalized measurements of independent nonscanning radiometers on different platforms observing the same geographical scene at the same time is described in this paper. This technique was applied to 1985, 1986, and 1987 measurements from the ERBS, NOAA-9, and NOAA-10 spacecraft to determine abrupt changes in the radiometric calibration procedure. The results for three years are presented.
