Abstract

The Clouds and Earth Radiant Energy System (CERES) program has the objective of producing a multi-decadal Climate Data Record (CDR) of Earth Radiation Budget (ERB) measurements. CERES Flight Model 6 was placed in orbit in November 2017 aboard the NOAA-20 spacecraft. FM-6 joined the FM-1 and FM-2 aboard the Terra, FM-3 and -4 aboard the Aqua, and FM-5 aboard the S-NPP spacecraft to seamlessly continue the Earth radiation budget CDR. FM-6 is the most highly calibrated CERES instrument due to improvements in the extensive pre-launch ground calibration campaign. Operations in orbit began with functional check-outs followed immediately by a period of intensive calibrations and validation checks and then transition to the long-term Cal/Val protocol. Initial results demonstrate agreement with ground calibrations within 0.5%. Operations to inter-calibrate with other CERES instruments will commence in the Spring of 2018. The current effort will document the results of the intensive post launch cal/val campaign completed in early 2018 as well as continued radiometric performance and including intercomparisons with other CERES instruments already on orbit.
