Abstract

Clouds and the Earth's Radiant Energy System (CERES) instruments are scanning radiometers on board the Terra and Aqua satellites since March of 2000 and June of 2002, respectively; hence, a continuous Earth's radiation budget dataset is more than a decade long. Since there are four CERES scanners in operation, it is important that their measurements are consistent. A focus of this paper is on putting Terra CERES on the same radiometric scale. The paper contains description of radiation budget experiments that are used in the process and a complete set of results. It is shown that one-time gain adjustments are sufficient in putting FM2 on the same radiometric scale as FM1, and they are to be used in processing the Edition 3 of CERES Erbe-like data products.
