SEAC4RS :The Southeast Asia Composition, Cloud, Climate Coupling Regional Study (SEAC4RS) offers the opportunity to address science questions that bridge the full spectrum of interests for the component programs of the Atmospheric Composition Focus Area. Broadly stated, these interests are to facilitate “progress in understanding and improving predictive capability for changes in the ozone layer, climate forcing, and air quality associated with changes in atmospheric composition.” Southeast Asia defines a region which stands out globally in satellite observations. For instance, during the Asian monsoon (July-September), MLS CO observations are consistently enhanced over southern Asia each year. These observations point to the region’s unique sensitivity to rapidly changing emissions of gas phase and aerosol pollutants in Asia. Simultaneously, this region also hosts one of the most complex meteorological and observing environments in the world. Understanding the sensitivity of this region to changes in climate and air quality requires knowlege of how dynamical, physical, chemical, and radiative processes are influenced by these emissions. |
Discover AQ :A challenge for Earth-observing satellites measuring air quality is to distinguish between pollution high in the atmosphere and that near the surface where people live and breathe. The summer 2011, NASA began a multi-year airborne field campaign to tackle this challenge. The project is called DISCOVER-AQ, which stands for Deriving Information on Surface conditions from Column and Vertically Resolved Observations Relevant to Air Quality.” NASA's Langley Research Center in Hampton, Va., is the lead center for the mission. |

Eucaari :The European Aerosol Cloud Climate and Air Quality Interactions (EUCAARI) project has been created to investigate the effects of aerosol particles on climate and air quality, thus, quantifying the effect of aerosols on the planet’s radiative balance as one of the most urgent tasks in our efforts to understand future climate change. As a whole, the contributions of the various aerosol sources, the role of long-range transport, and the contribution of primary and secondary particulate matter to the ambient aerosol concentrations over Europe are still not well known. Particularly uncertain are aerosol parameters influencing the radiative balance and properties of clouds, such as the number size distribution, chemical composition and particle mixing state. The EUCAARI observational system consists of long-term and spatially extensive surface-based measurements, including the European network of supersites for aerosol research (EUSAAR). In addition, the use of satellites contributes to understand regional aerosol variations and provide the somewhat the distribution of aerosol and cloud properties. Within the frame of this project an intensive measurement campaign including the deployment of European research aircraft (DLR Falcon-20, British Bae-146, NERC Dornier, French ATR-42, and others) has been performed in May 2008. The French ATR-42 has been particularly equipped with state of the art aerosol and cloud instrumentation. |

AMMA :The African Monsoon Multidisciplinary Analysis (AMMA) program was designed to improve our knowledge on the African monsoon and its variability. A detailed description on the project is available at www.amma-international.org/. One of the objectives of the project was to investigate the cloud-aerosol interactions and particularly the role of aerosols in the African monsoon system. Several intensive campaigns of aerosol and cloud measurements were carried out between 1 June and 25 August 2006 in the western African region including both airborne (DLR Falcon-20, British Bae-146, French ATR-42, and others) and ground measurements. |
