International Global Atmospheric Chemistry - IGAC

It is now well recognized that human activities have perturbed the chemical composition of the atmosphere on local, regional and global scales. On regional scales, air pollution is a serious and growing problem in many parts of the world. In the industrialized mid-latitudes of the Northern Hemisphere, elevated concentrations of ground-level ozone and particulate matter are of concern to human health and agriculture perspectives. In other regions, the development and growth of mega-cities must be considered in studies of regional and global atmospheric chemistry. The IGAC project examines the atmospheric chemistry issues facing society, as well as the challenges of studying and managing an integrated Earth System. IGAC was launched in 1988 and is co-sponsored by the Commission on Atmospheric Chemistry and Global Pollution (CACGP) of the International Association of Meteorology and Atmospheric Sciences (IAMAS).
