Early trends on the Clouds and the Earth's Radiant Energy System (CERES) instruments' performances using in-flight calibration sources, for Earth Science Enterprise (eSE) TERRA mission

摘要

Clouds and the Earth's Radiant Energy System (CERES) instrument, with it's three scanning thermistor bolometers, was designed to provide accurate measurements for the long-term monitoring of Earth's radiation energy budget. The sensors measure broadband radiances in the shortware (0.3-5.0 micrometers), total (0.3->100 micrometers) and 8-12 micrometer water vapor window regions. Two of the CERES instruements, Flight models 1 and 2 (FM1 and FM2) are scheduled for launch aboard the Earth Science Enterprise (eSE) Terra Spacecraft in November 1999.
