Clouds and the Earth's Radiant Energy System, CERES, monitors solar energy reflected from the Earth and heat energy emitted from the Earth. In this image, heat energy radiated from the earth is shown in varying shades of yellow, red, blue and white. The brightest yellow areas, such as the Sahara Desert and Arabian Peninsula, are emitting the most energy out to space, while
the dark blue polar regions and bright white clouds are the coldest areas on
Earth, and are emitting the least energy. The animation shows roughly a week of CERES data.
