Copernicus Atmosphere Monitoring Services
Sentinel missions dedicated to atmospheric composition
Services Component – led by EC• Produces information services • Relies on in-situ & space components
In-situ Component – led by EEA• Observations mostly national responsibility
Space Component – led by ESA• Sentinels – satellite missions developed specifically for
Copernicus
