|New functionalities in v2020 version|
- WRF-CHIMERE online coupled model: The model can be used offline (with interfaces for ECMWF, WRF) or online coupled with WRF, for direct and indirect aerosol effects. Please read the WRF public notice
- Natural emissions: with the addition of dimethyl sulfide, new schemes for sea-salt, improvements for mineral dust and biomass burning and addition of NOx from lightning.
- Aerosols chemistry: with the addition of the SOAP thermodynamical model, as well as Volatility Basis Set scheme and the new H2O aerosol scheme for organic aerosols
- Subgrid scale variability: for cells with anthropogenic emissions with several activity sectors, it is possible to have pollutant concentrations for each.
- Vertical transport: Updated strategy for vertical advection of pollutants and implementation of the Despres and Lagoutiere (1999) antidiffusive advection scheme
- CHIMERE is an open source multi-scale chemistry-transport model designed to produce (i) accurate analysis of pollution episodes, (ii) daily forecasts of ozone, aerosols and other pollutants, (iii) long-term simulations (entire seasons or years) for emission control scenarios.
- CHIMERE runs over a range of spatial scale, from the hemispheric to the urban scale with resolutions from 1km to several degrees.
- CHIMERE has many different options for simulations which make it also a powerful research tool for testing parameterizations. CHIMERE is a parallel model that has been tested on machines ranging from desktop PCs running the GNU/Linux operating system, to massively parallel supercomputers (HPCD at ECMWF).
- On this server, documentation and source codes are free to access. The model is proposed with a complete environment: global model climatologies for boundary conditions, programs for emissions (anthropogenic with emisurf, biomass burning).
- To learn how to use and modify the model, training sessions are organized once a year
