Development of an air quality forecast system for air quality survey networks
The system development is half-funded by AAM and the other half by ACRI
Collaborations : IPSL/LISA
Links :NCAR, which developed MM5 modelNCEP, which distribute GFS productsINERIS, which distribute PREV’AIR outputs

Development of an air quality forecast system for air quality survey networks
System architecture
Computer 1 mono-processor PC Windows NT • Input process (User interface developped in JAVA)• Input data download• Processing control (scheduler) • Temporary archive• Post processing (2D map generation, GIS export and web publication)
2 bi-processor PC, Linux (use of the MPP version of MM5, internal domains of CHIMERE run in parallel)• 1 PC for forecast• 1 PC for scenario

Development of an air quality forecast system for air quality survey networks
System flexibility
• Based on standard formats => new models could be integrated very simply– GRIB for meteorological inputs– NETCDF conversion for model outputs– SHAPEFILE for GIS
• Based on self describing user interface

Development of an air quality forecast system for air quality survey networks
• AIR ALPES MEDITERRANEE, AIRES since June 2004 at ACRI
• AIR PAYS DE LA LOIRE operated during summer 2004
• ASPA since December 2004
Operational platforms

Development of an air quality forecast system for air quality survey networks
• AIR ALPES MEDITERRANEE : AIRES SYSTEM
– ESCOMPTE emission inventory (IOPs 2001 emissions used last summer completed with EMEP). Actualised in the next few days with the new 3km PACA inventory.
– Calibration phase with LMD during June 2004
– Validation by :
Participating to the ESCOMPTE modelling exercise
Evaluating Summer 2004 results

Development of an air quality forecast system for air quality survey networks
• Escompte modelling exercise configuration (sensitivity tests) :
– Continental CHIMERE run for boundary conditions/PREVAIR
– MM5 forced by NOGAPS data (FNMOC)/GFS
– Adaptation of the MM5 terrain processor to CORINE LAND COVER/USGS and CRIGE data/GTOPO30
– EMEP integration INERIS routine adapted to CORINE LAND COVER data : more precise on regional scale (industries, urban areas…)/GLCC
– Plume elevation treated for punctual emissions (CALGRID formulation)/chimney height
AIR ALPES MEDITERRANEE, AIRES

Development of an air quality forecast system for air quality survey networks
AIR ALPES MEDITERRANEE, AIRES• Ozone concentrations highly dependent on
dynamics :
– Example : system configuration comparisons LISA/ACRI during Escompte modelling exercise (ECMWF/NOGAPS).
• Importance of local emission inventory for regional purposes (comparisons between EMEP/local inventory)
• For IOP1, extension (to the East and to the North) of the 9km resolution domain for boundary conditions

Development of an air quality forecast system for air quality survey networks
ASPA
• INTERREG III project framework
• Extension of the previous forecast system to Oberrhein region– High resolution meteo forecast– Extension of the CHIMERE domain– New emission inventory
21 mars 2005
Development of an air quality forecast system for air quality survey networks
ASPA
• Validation in collaboration with EPFL– 2 test-cases corresponding to INTERREG III
measurement campaign (june 2003)– 2 test-cases during the generalised IOPs of
august 2003• For model parameterisation• For estimation of transboundary ozone versus local
ozone production

• AIR PAYS DE LA LOIRE :
– Emission inventory using AIREMIS outputs (developed in the SAMAA modelling system) from the APL august 2003 ozone simulations.
– The Pays de la Loire emission inventory completed by EMEP emissions
– Validation by :
Evaluating Summer 2004 results : performed by APL and analysed by ACRI-ST
