The chemistry-transport model CHIMERE (IPSL/LMD)
A short history of the tool:
1997: First version: the Paris area in a box-model1998: The first experimental web site for the ESQUIF field campaign1999: cartesian grids2001: European experimental forecast with PIONEER project2004: implementation of aerosol module2006: development of the parallel version of the code
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
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.
Example of daily forecast experimental (at LMD):
- France (GEMS)- Africa, Atlantic and Europe: CHIMERE-DUST for minreal dust
operational: PREVAIR french nationla plat-form (INERIS)

CHIMERE users in Europe
The chemistry-transport model CHIMERE (IPSL/LMD)
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
