The two CERES instruments on Terra successfully opened their contamination cover doors on Friday, February 25. A few hours later, they began to scan the Earth, making measurements of the reflected solar flux and emitted terrestrial flux that make up the Earth’s radiation budget. Both instruments appear to be working very well. In normal operation one instrument will scan perpendicular to the Terra ground track, in order to spatially sample the Earth. The other instrument samples the angular distribution of radiation. These two Terra instruments join a previous CERES scanner on the Tropical Rainfall Measuring Mission (TRMM), which was launched on November 27, 1997. They complement TRMM by extending the observations to cover the globe and by improving sampling of the large diurnal cycle of radiation.
