    • CHIMERE 2008: What's new?

    New functionality:
    • Integration of the MEGAN biogenic emission model
    • Automatic preparation of the file LANDUSE_ from the original GLCF global land use
    • Meteorological interface to the WRF model
    • Possibility to use aerosol boundary and initial conditions from the LMDz model output
    • A new mode of exachim to display various data slices by a simple mouse click
    Process changes
    • Updated Secondary Organic Aerosols (SOA) chemistry (full MEGAN SOA scheme)
    Computational changes
    • New format of the emissions interface emiSURF and prepemis (species per species)
    • New format of boundary and initial conditions (species per species)
    • Running Open MPI or LAM depending on user system settings.
    • New top calling script chimere.sh (possibility for several nested domains)
    • New chimere-run.sh (possibility for separate compilation and module execution)
    Physics and numerics in short

    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.
