Abstract

Beginning in 1984, three Earth Radiation Budget Experiment (ERBE) spacecraft were launched to measure the Earth's radiation budget components: Solar-incident, Earth-emitted, and Earth-reflected radiation. The National Aeronautics and Space Administration's Earth Radiation Budget Satellite was launched in 1984 in a low-inclination orbit, and the National Oceanic and Atmospheric Administration's NOAA-9 and NOAA-10 satellites were launched in Sun-synchronous polar orbits in 1984 and 1986, respectively. This paper describes the method used for correcting for changes in the gains and offsets used for determining the final count conversion coefficients used in processing the in-flight calibration data. We also describe a technique for the determination of WFOV shortwave offsets which proxies for nighttime offsets during months of continuous daytime only orbits near sunrise and sunset when no nighttime measurements are available. The final result covering the period of 1984 through 1991 are discussed in this paper.
