• The system development is half-funded by AAM and
  the other half by ACRI
• Collaborations IPSL/LISA
• Links
• NCAR, which developed MM5 model
• NCEP, which distribute GFS products
• INERIS, which distribute PREVAIR outputs

System description

• Emission-dispersion modelling Platform for
  operational production of temporal and spatial
  distribution of primary and secondary pollutants
• Main characteristics
• Independent from the meteorological and
  dispersion software
• Scenario and forecast platform
• MM5 and CHIMERE user interface

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

6
System flexibility

• Based on standard formats gt 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

7
Operational platforms

• AIR ALPES MEDITERRANEE, AIRES since June 2004 at
  ACRI
• AIR PAYS DE LA LOIRE operated during summer 2004
• ASPA since December 2004

8
Main features

• 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

AIR ALPES MEDITERRANEE, AIRES

• 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

• 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

12
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

13
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/Atmo Auvergne

• 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
