Paper Abstract

The Clouds and Earth Radiant Energy System (CERES) Flight Model FM-1 and FM-2 sensors aboard the Terra and the FM-3 and FM-4 sensors aboard the Aqua spacecraft have provided the first decade of observations of quality suitable for the Earth Radiation Climate Data Record (CDR). To assure continuity of this CDR the CERES FM-5 sensor will fly on the NPP spacecraft, scheduled for launch in October 2011. The methods for calibrating the FM-5 in orbit and validating the results so as to maintain the required level of accuracy and traceability are described. These methods include use of on-board calibration sources and a number of tests devised for FM-1 through -4. In addition, comparisons of measurement by the newly calibrated FM-5 with (nearly) coincident measurements by the older CERES instruments on Terra and Aqua provide an opportunity to investigate the effects on the instruments and the on-board calibration devices of a decade of operating in space.
