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

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

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

Current Air Quality Services and Products

• 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

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

• 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

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
