Paper 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, their 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 placing two Aqua CERES sensors on the same radiometric scale as FM1 on Terra. The paper contains a description of radiation budget experiments that are used in this task, and a complete set of results. It is shown that one-time adjustments to gains and spectral response functions are sufficient in putting FM3 and FM4 on the same radiometric scale as FM1 at the beginning of their mission. The Edition 3 of ERBE-like data products use derived corrections for Aqua CERES sensors.
