Provision of daily operational spatial air quality data from the ESA Project:
PROMOTE
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
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
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
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

• Forecasting/Analysis Products @ various spatial scales– State of near-surface air quality– Forecast of near-surface air quality
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)
Gas Retrievals: Tropospheric NO2

• Forecasting/Analysis Products @ various spatial scales– State of near-surface air quality– Forecast of near-surface air quality
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
Aerosol Optical Depth (AATSR)
Spatial resolution: 10x10 km2, 1x1 km2 on request
Validation vs collocated AERONET sites
Current Air Quality Services and Products

• 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
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
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

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
