    Short model description
    The CHIMERE multi-scale model is primarily designed to produce daily forecasts of ozone, aerosols and other pollutants and make long-term simulations (entire seasons or years) for emission control scenarios. CHIMERE runs over a range of spatial scale from the regional scale (several thousand kilometers) to the urban scale (100-200 Km) with resolutions from 1-2 Km to 100 Km. On this server, documentation and source codes are proposed for the complete multi-scale model. CHIMERE proposes many different options for simulations which make it also a powerful research tool for testing parameterizations, hypotheses.

    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). A minimal set of 1 Gb RAM is necessary. Software required is a Fortran 90 compiler (ex: g95, ifort, pgf90 or xlf), some GNU utilities (gmake and gawk) and an MPI library. Graphical interfaces are available using the GrADS or GMT freewares.
