Abstract

The Clouds and Earth’s Radiant Energy System (CERES) project operates six instruments that provide a continuous record of the Earth’s radiation budget (ERB) at the top of atmosphere (TOA). The instruments are flying on the Terra, Aqua, SNPP and NOAA-20 spacecraft. The CERES instruments on Terra and Aqua have completed twenty years of continuous operations. Each instrument is calibrated and characterized on the ground before launch. Post launch, the calibration is conducted using on-board calibration sources and the performance of the instrument is validated using vicarious approaches using both Earth and celestial targets. In this paper, we describe the calibration and validation approach and demonstrate the performance of the CERES instruments on the Terra and Aqua spacecraft over the twenty-year period since launch.
