Clouds and the Earth's Radiant Energy System (CERES)

Eye on Earth's Radiant Energy System
The most precisely calibrated radiometer ever to fly in space, the Clouds and the Earth's Radiant Energy System (CERES) instrument is measuring emitted and reflected radiative energy from the surface of the Earth and the atmosphere. Previous space-based observations have shown that the role of clouds, which reflect, absorb, and trap radiant energy; is critical in maintaining the Earth's radiant energy balance, a balance threatened by the build-up of carbon dioxide and other greenhouse gases in the atmosphere. The Northrop Grumman-built CERES is providing scientists with the most accurate eye ever for measuring clouds and their impact on Earth's radiant energy system.
