The chemistry-transport model CHIMERE (IPSL/LMD)?
A communitary model in free access
http//www.lmd.polytechnique.fr/chimere Developed
in France, used in the whole Europe.
CHIMERE is a chemistry-transport model for the
calculation of concentrations fields as ozone,
NOx, COVs, aerosols, dust... at the regional
scale, for long periods (several years) wuth an
hourly resolution

• A short history of the tool
• 1997 First version the Paris area in a
  box-model
• 1998 The first experimental web site for the
  ESQUIF field campaign
• 1999 cartesian grids
• 2001 European experimental forecast with PIONEER
  project
• 2004 implementation of aerosol module
• 2006 development of the parallel version of the
  code

The chemistry-transport model CHIMERE (IPSL/LMD)?

• As a communautary tool, CHIMERE represents
• More than 100 users
• More than 20 institutes are using CHIMERE for
  daily forecast
• More than 35 institutes for research
• More than 50 papers in peer-reviewed journals
• Involved in numerous European projects such as
  GEMS, PROMOTE, City-Delta, Euro-Delta, CIRCE,
  AMMA, GEOMON, NATAIR.
• Used for analysis, forecast, pollution peaks and
  trends, direct or adjoijnt modelling, data
  assimilation.

2008 Current developments Open the model to
other domains than Europe A meso-scale window
in any place of the world - Several
meteorological forcings ARPEGE, NCEP, MM5, WRF,
ECMWF/IFS for analysis and forecast -
Implementation of LMDz/IPCC for regional climate
changes studies - Several boundary conditions
gas, aerosols, dust and fires in development -
Biogenic and anthropogenic emissions for Europe
only to 'regional windows' everywhere in the
world with EDGAR and MEGAN databases. -
Implementation of systematic comparisons to
satellite products (AOT, Scattering Ratio with
CALIOP)? Increase the small scale knowledge
Sub-grid scale variability, urban processes
modelling for health impact studies
