  1. Provision of daily operational spatial air quality data from the ESA Project: PROMOTE E. Paliouras (DLR-DFD) & the PROMOTE consortium eleni.paliouras@dlr.de http://www.gse-promote.org 10th EIONET Workshop Vilnius, Lithuania 18 October 2005

  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 Elementby constructing & delivering a sustainable & reliableoperational 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

  4. PROMOTE Core Users - AQ • National Environmental Agencies • Austria (UBA) • France (ADEME) • Ireland (EPA) • The Netherlands (MNP) • Regional & Local Environmental Agencies • Lombardia and Piemonte, Italy (ARPA) • Northrhein-Westfalia, Germany (LUA) • Île de France, France (AirParif) • London Borough of Croydon • Central Macedonia, Greece (RCM) • Research Institutes • EMPA – Swiss Federal Lab for Material Testing and Research • INERIS – within French Ministry of Ecology • JRC – Institute for Environment and Sustainability (IES) • NILU – Norwegian Institute for Air Research • VITO – Flemish Institute for Technological Research

  5. Current Air Quality Services and Products • Monitoring Products – Satellite based • Gas Retrievals - global • Tropospheric NO2 • Total Column HCHO, CO, SO2 • Aerosol Services – global and regional • Aerosol Optical Depth and Aerosol Type indicator • Sahara dust indicator • Forecasting/Analysis Products @ various spatial scales • State of near-surface air quality • Forecast of near-surface air quality

  6. Current Air Quality Services and Products • Monitoring Products – Satellite based • Gas Retrievals - global • Tropospheric NO2 • Total Column HCHO, CO, SO2 • Aerosol Services – global and regional • Aerosol Optical Depth and Aerosol Type indicator • Sahara dust indicator • Forecasting/Analysis Products @ various spatial scales • State of near-surface air quality • Forecast of near-surface air quality

  7. Gas Retrievals: Tropospheric NO2 • Global coverage - GOME and SCIAMACHY sensors • Target Uses • Trend analysis via monthly or annual means • Model input via NRT information • Three algorithms being considered and compared with some degree of complementarity: • IUPB Limb/nadir Based on the limb/nadir matching technique (tropospheric slant columns are directly measured) • KNMI/BIRA TM4 Global product (GOME, SCIA, OMI) • DLR ROSE/EURAD Regional product = optimized accuracy for Europe (SCIAMACHY, GOME)

  8. Gas Retrievals: Tropospheric NO2

  9. Current Air Quality Services and Products • Monitoring Products – Satellite based • Gas Retrievals - global • Tropospheric NO2 • Total Column HCHO, CO, SO2 • Aerosol Services – global and regional • Aerosol Optical Depthand Aerosol Type indicator • Sahara dust indicator • Forecasting/Analysis Products @ various spatial scales • State of near-surface air quality • Forecast of near-surface air quality

  10. Aerosol Optical Thickness and Type • Various services being tested including global and local coverages • Retrievals from daily acquisitions of multiple sensors • Synergistically from GOME/ATSR-2 or SCIAMACHY/AATSR • AATSR alone • MERIS • MODIS • Target Uses • Global coverage and climatologies for monitoring • NRT retrievals over Europe as input to AQ models

  11. Aerosol Optical Depth (AATSR) • Spatial resolution: 10x10 km2, 1x1 km2on request Validation vs collocated AERONET sites

  12. Current Air Quality Services and Products • Monitoring Products – Satellite based • Gas Retrievals - global • Tropospheric NO2 • Total Column HCHO, CO, SO2 • Aerosol Services – global and regional • Aerosol Optical Depth and Aerosol Type indicator • Sahara dust indicator • Forecasting/Analysis Products @ various spatial scales • State of near-surface air quality • Forecast of near-surface air quality

  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: O3, NO2, PM10, SO2, 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

  17. PACA region 9 km x 9 km Re-distributed EMEP ESCOMPTE area 3 km x 3 km Re-distributed EMEP AQ Forecasts in Different Domains

  18. AQ Forecasts in Different Domains

  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
