Abstract

The SCAnner for RAdiation Budget (ScaRaB) 3 instrument is aboard the Megha-Tropique spacecraft. The CERES Flight Model 5 was recently placed in orbit aboard the NPP spacecraft to replace the CERES FM-1 through -4 aboard the Terra and Aqua spacecraft which have provided Earth radiation budget measurement for twelve and ten years. The CERES instruments have been rotated in azimuth so the CERES can observe the same scene in the same direction as ScaRaB, thus both instruments measure the same radiance for shortwave (reflected solar) radiance and for longwave (Earth-emitted) radiance. The data collected in this manner serves to validate all of these instruments. The geometry of the operation of CERES as constrained by the orbits is described.
