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

– 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
– KNMI/BIRA TM4
– DLR ROSE/EURAD
Based on the limb/nadir matching
technique (tropospheric slant
columns are directly measured)
Global product (GOME, SCIA, OMI)
Regional product = optimized
accuracy for Europe (SCIAMACHY,
GOME)

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

• Total Column HCHO, CO, SO2
– Aerosol Services – global and regional
• Aerosol Optical Depth and Aerosol Type indicator
• Sahara dust indicator

– 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
