2. GSEs: Background ESA GMES contribution : GSE (GMES Service Element) –GMES-applicable capabilities in Europe already exist target operational & sustainable information services –focus mainly on services using Earth Observation sources draw on results obtained from present EO satellites and provide recommendations for future EO systems –GSEs start with a 20-month Consolidation Stage intended to evaluate a large set of candidate services –Full-fledged operational services for an Implementation Stage with funding of 3 years

3. GSE for Atmospheric Monitoring PROMOTE Mission: To deliver the Atmosphere GMES Service Element by constructing & delivering a sustainable & reliable operational service to support informed decisions in particular on atmospheric policy issues 4 themes selected based on identifiable user requirements and maturity or promise of satellite and ground-based observations –Stratospheric Ozone –Surface UV Radiation –Air Quality –Greenhouse Gases and Aerosols Project information and current product portfolio at: www.gse-promote.org

13. Near-Surface Air Quality Provide indicators of near-recent, current, and forecasted states of air quality at the surface using models, ground data and satellite data Operational systems at regional scale –Prev’Air –EURAD provides analyzed maps of near-surface levels of: O 3, NO 2, PM10, SO 2, CO based on assimilation of ground observations Operational systems at local and urban scales –SE Mediterranean –SE France based on CHIMERE model –Greater London Area, based on ADMS Urban, called YourAir

14. Forecasting of Near-Surface Air Quality Provide up to 4-day forecasts of ground level air quality using models in combination with ground & satellite data Three geographical scales using several modeling systems –Hemispheric/Continental –Regional (National and trans-national) –Local (City-scale) Assimilation of ground and satellite-based data is undergoing investigation within as well as outside PROMOTE –Availability of ground-based data in near-real time across Europe is limited –a European-wide strategy to foster increased availability would be welcomed

19. Forecasting of Near-Surface Air Quality Provide up to 4-day forecasts of ground level air quality using models in combination with ground & satellite data Three geographical scales using several modeling systems –Hemispheric/Continental –Regional (National and trans-national) –Local (City-scale) Assimilation of ground and satellite-based data is undergoing investigation within as well as outside PROMOTE –Availability of ground-based data in near-real time across Europe is limited –a European-wide strategy to foster increased availability would be welcomed

20. Summary PROMOTE is one of the major ESA GMES initiatives –only one related to atmosphere Finishing Consolidation Stage – formulating plans for Implementation Stage –looking for partner organizations interested in using results of spatial modeling of air quality requires availability of near-real time ground data Availability of ground-based data, such as AirBase, very useful for verification of current systems Availability of NRT ground-based data critical for improved forecasts at higher spatial resolution
