2005 CHIMERE Workshop 9
Project IRENI (sub project 2B - action 1 - axis 1)• Modeling of reactivity and dispersion of atmospheric
pollutants in the Nord pas de Calais. Industrial emissions study on the french coastal Channel area
Project INRETS • Modeling assessment of the role of vehicular emissions in
the formation of tropospheric ozone and related species
Project CERPA• Mapping Aerosol Risk Indices
Regional projects using CHIMERE
2005 CHIMERE Workshop 10
Project IRENI (Institut de Recherches en Environnement Industriel)
Collaborations :
PC2A (UAM and CHIMERE models)
ELICO-UMR 8013 (Meso NH model)
ATMO Nord Pas de Calais (air quality network)
Objective : To develop a scientific strategy of environmental diagnosis and remediation of the air quality on our region
Work program : (beginning date : october 2005)• Running of the models (modeling domain, grid, time step, boundary conditions [Prev’air, Esmeralda], emission inventories, complementary measurements…)• Modeling using 3 domains (nesting)• Validation of modeling by comparison with the air quality measurements (network, field campaign, lidar …)• Inverse modeling, remediation, prediction

2005 CHIMERE Workshop 11
Project INRETS (Institut National de REcherches sur les Transports et leur Sécurité)
Collaborations :
PC2A and INRETS (Lyon-Bron)
Aim of the work : answer to the question « What is the relative impact of vehicular emissions on the formation of tropospheric oxidants »
Work program : (beginning date : october 2005)• Calculate the vehicules emissions with ARTEMIS model• Using an exhaustive molecular emission inventory of ozone precursors (up to 60 VOC)•Various scenarios of reduction in the emissions of VOC and/or NOx from vehicles will be considered , in order to calculated the corresponding percent of variation in O3 formation
Calculation of number of kilometers on the section
Application of the EF (g/km)for any pollutants and any engine
technology
Linear emissions
Gridded emissions
Major roads of the area
2005 CHIMERE Workshop 12
Project CERPA (Cartographie de l’Exposition aux Risques des Populations aux Aérosols )
Collaborations :
PC2A (USTL), LISE ( ULCO), HYGEOS, ATMO and APPA
Aim of the work : To deliver a data base which allows to study the health impact of the particles in a given area (Nord Pas de Calais) through the production of risk indices.
Work program : (beginning date : october 2005)• A consolidation of the PM product as derived from the Earth Observation• A modeling of the PM generation using the CHIMERE model• A joint activity with the health autorities in order to define suitable risk index for the populations regarding exposures to particules
This project will contribute to valorise an ending INTERREG -III project
(EXPER/PF)
2005 CHIMERE Workshop 13
Future developments on CHIMERE
In order to achieve the 3 projects presented, the code will be optimized:
• on one hand the chemical module :
use of explicit mechanisms
use of radiative codes or irradiance measurements for photolysis calculation
• on the other hand we plan to parallelize the code in order to reach a better space resolution using a finer scale (500 m) with a convenient computer time which should make more credible to use CHIMERE as a predictive tool.
