Solar radiation enters the Earth's atmosphere with a portion being scattered by clouds and aerosols.

What is CERES?

The Clouds and the Earth's Radiant Energy System (CERES) experiment provides radiometric measurements of the Earth's atmosphere from three broadband channels and is a follow-on to the Earth Radiation Budget Experiment (ERBE) mission. CERES products include both solar-reflected and Earth-emitted radiation from the top of the atmosphere to the Earth's surface. The CERES experiment will lead to a better understanding of the role of clouds and the energy cycle in global climate change.
