Description
The Cloud's and the Earth's Radiant Energy System (CERES) is a 3-channel radiometer measuring reflected solar radiation in the 0.3-5 µm wavelength band, emitted terrestrial radiation in the 8-12 µm band, and total radiation from 0.3 µm to beyond 100 µm. These data are being used to measure the Earth's total thermal radiation budget, and, in combination with MODIS data, detailed information about clouds. The first CERES instrument was launched on the Tropical Rainfall Measuring Mission (TRMM) satellite in November 1997 as CERES-PFM; the second and third CERES instuments were launched on the Terra satellite in December 1999 as CERES-FM1 AND -FM2; and the fourth and fifth CERES instruments are on board the Aqua satellite, as CERES-FM3 and CERES-FM4.

Aqua carries two CERES instruments, the fourth and fifth CERES to fly in space. The TRMM and Terra CERES have obtained levels of accuracy never before achieved for comprehensive Earth radiation-budget measurements. All the CERES instruments have the capability of operating in either of two scanning modes: fixed azimuth plane scanning, where the scan lines are perpendicular to the path of the satellite, and rotating azimuth plane scanning, where the scan lines are at wide range of angles with respect to the satellite's path. The paired CERES on Terra and on Aqua provide both of those missions with the possibility of coincident fixed azimuth plane scanning from one CERES and rotating azimuth plane scanning from the other CERES, enhancing the quality of the final products.
