The World Meteorological Organization's (WMO) Global Atmosphere Watch Programme (GAW) has been established to provide information on changes in the chemical composition and related physical characteristics of the atmosphere to improve understanding and to predict future states of the earth's system on a global and regional basis. GAW coordinates the state-of-the-science measurements of the chemical and physical constituents of the atmosphere at levels extending from the surface to the stratosphere and at some of the most difficult locations on earth. These include solar radiation, specifically ultraviolet (UV) radiation, measurements.

Elle permet de tirer parti des progrès scientifiques les plus récents pour effectuer des mesures concernant un certain nombre de constituants physiques et chimiques de l'atmosphère, le plus souvent de faible concentration, à des niveaux allant de la surface jusqu'à la stratosphère et dans certains endroits de la Terre les plus difficiles d'accès.

Key term(s)
  • constituants physico-chimiques de l'atmosphère
