The CHIMERE model has been under continuous development for many years, and has been used to carry out numerous analyses of air pollution cases, future scenarios and parameterization developments. The model is updated regularly, and a new version is released under the free GPL license every 2 or 3 years. This poster presents the new 2023 version released in December. It contains new schemes (emissions, turbulence, chemistry) but also a coupling with the XIOS code and the SSH-aerosol aerosol module, and the recent version of WRF 4.3 for direct and indirect aerosol effects. In terms of correlation and bias, this version is better than its predecessor for simulating gases and aerosols such as O3, NO2, PM10 and AOD. It is also faster, as it runs simulations 40% faster than the previous version.
