5. March 2003GMES-GATO presentation at kick-off5 Main objective To develop a strategy for global observations of atmospheric composition within GMES: Stratospheric ozone,Stratospheric ozone, Greenhouse gasesGreenhouse gases Tropospheric pollution (urban, rural, marine)Tropospheric pollution (urban, rural, marine) Natural hazards, e.g.volcanoesNatural hazards, e.g.volcanoes Atmosphere influence on surface obs.Atmosphere influence on surface obs. Long term observations and the effective use of near real-time data will be addressed.
