+ Clouds and the Earth's Radiant Energy System (CERES)
CERES provides both solar-reflected and Earth-emitted radiation from the top of the atmosphere to the surface. It also determines cloud properties including the amount, height, thickness, particle size, and phase of clouds using simultaneous measurements by other instruments. These measurements are critical for understanding cloud-radiation climate change and improving the prediction of global warming using climate models. CERES is flying, or will fly, on the Tropical Rainfall Monitoring Mission (TRMM), Terra, and EOS-PM.   » Read more …

+ NASA's Earth Science Enterprise
The Earth Science Enterprise plays a vital role in three key challenges facing America and the world today: climate change, homeland security, and educating the next generation of explorers. Improving life on planet Earth is foremost in NASA's Vision, and the central work of NASA's Earth Science Enterprise. NASA research yields information about Earth's land, atmosphere, ice, oceans and life that is obtainable in no other way.   » Read more …
