The Global Atmosphere Watch (GAW) is a WMO Programme to provide scientific data and information on the chemical composition of the atmosphere and its natural and anthropogenic change, and to improve the understanding of interactions between the atmosphere, the oceans and the biosphere. source: WMO Website http://www.wmo.int/pages/prog/arep/gaw/gaw_home_en.html
