The Arctic is undergoing significant environmental changes related to global climate change. Now, NASA is extensively studying the role of air pollution in this climate-sensitive region as part of the ARCTAS field campaign, the largest airborne experiment ever to do so.
The Glory mission was intended to improve our understanding of Earth's energy balance and the role of aerosols in climate. The spacecraft was launched March 4, 2011, but did not achieve orbit due to the failure of the payload faring to open.
The current incarnation of the GISS series of coupled atmosphere-ocean models is now available. Called ModelE, it provides the ability to simulate many different configurations of Earth System Models - including interactive atmospheric chemsitry, aerosols, carbon cycle and other tracers, as well as the standard atmosphere, ocean, sea ice and land surface components.
ISCCP was established as part of the World Climate Research Programme to collect and analyze satellite radiance measurements to infer the global distribution of clouds, their properties, and their diurnal, seasonal, and interannual variations. The resulting datasets and analysis products are used to improve understanding and modeling of the role of clouds in climate, with the primary focus being the elucidation of the effects of clouds on the radiation balance. The Global Processing Center for ISCCP is located at the NASA Goddard Institute for Space Studies.
NASA’s Precipitation Measurement Missions – TRMM and GPM – provide advanced information on rain and snow characteristics and detailed three-dimensional knowledge of precipitation structure within the atmosphere, which help scientists study and understand Earth's water cycle, weather and climate.
