Regional projects using CHIMERE

• 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

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 Prevair,
  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

11

• Project INRETS (Institut National de REcherches
  sur les Transports et leur Sécurité)

Calculation of number of kilometers on the section
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
Application of the EF (g/km)for any pollutants
and any engine technology
Linear emissions

• 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

Gridded emissions
Major roads of the area

• Project CERPA (Cartographie de lExposition 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.
This project will contribute to valorise an
ending INTERREG -III project (EXPER/PF)

• 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

Conclusion

• 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.
