Overview of the Atmospheric Research and Environment Programme (AREP)
Within the United Nations , it is the responsibility of WMO to provide the authoritative voice on the state and behaviour of the atmosphere and climate of the Earth. To this end, the Atmospheric Research and Environment Programme department co-ordinates and stimulates research on the composition of the atmosphere and weather forecasting, focusing on extreme weather events and socio-economic impacts. AREP supports global research initiatives under programmatic guidance from the Commission for Atmospheric Science (CAS). It does this through two programmes: the Global Atmosphere Watch (GAW) and the World Weather Research Programme (WWRP) including THORPEX. WWRP supports research to develop improved and cost-effective forecasting techniques and their application for socio-economic benefit and in decision-making. Activities are conducted related to synoptic forecast verification and linking forecast products to societal benefit areas. AREP leads the WMO Sand and Dust Storm Warning System. It also supports sound science practices in weather modification research. The WWRP programme is closely linked to the World Climate Research Programme with which it shares support of the Working Group on Numerical Experimentation (WGNE). GAW focuses on the coordination and application of global observations of atmospheric greenhouse gases, ozone, ultraviolet radiation, aerosols, selected reactive gases, precipitation chemistry and the GAW urban meteorology and environment project (GURME). It supports international conventions on ozone depletion, climate and long-range transport of air pollution. With community support it issues WMO Ozone Bulletins and Greenhouse Gas Bulletins.
