The chemistry-transport model CHIMERE (IPSL/LMD)
A communitary model in free access 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. Vertical cross-section of a dust event over Ukraine (March 2007) [Bessagnet et al., 2008] 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 One of the forecast web sites

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
