NASA has granted a small team of University of Arizona researchers $3.46 million over 11 years to help monitor Earth s radiation budget, which is the balance between the absorbed solar energy on the surface and the infrared radiation Earth emits back into space. When Earth emits less than it absorbs, it leads to global warming.

The grant is part of the larger $150 million Libera mission that will orbit Earth to measure Earth s energy. Libera will launch in 2027 to continue the work of NASA s outgoing mission CERES, short for Clouds and the Earth s Radiant Energy System. Ceres, the Roman goddess of agriculture, is Libera s mother in Roman mythology.
New findings about tiny aerosols will greatly improve climate models
January 22, 2021 SHARE New results from an atmospheric study over the eastern North Atlantic reveal that tiny aerosol particles which seed clouds can form out of next-to-nothingness over the open ocean.

New results from an atmospheric study over the eastern North Atlantic reveal that tiny aerosol particles that seed clouds can form out of next-to-nothingness over the open ocean.
This “new particle formation” occurs when sunlight reacts with molecules of trace gases in the marine boundary layer, the atmosphere within about the first mile above Earth’s surface. The findings will improve how aerosols and clouds are represented in models that describe Earth’s climate so scientists can understand how the particles and the processes
