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

21 mars 2005

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

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

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
