How to contact the developers?

You can contact the developers if you have questions about compilation, databases, parameterizations, etc.:

If you have a technical question, please follow this guideline:

  1. Re-compile and re-run the code using the --devel option. This will give you the code line number where the crash occurred and it could help you and us understand what goes wrong.
    1. Add --devel at the end of the compilation command line, for example:
      ./build-chimere.sh --no-oasis --devel
    2. Add --devel at the end of the execution command line:
      ./chimere.sh -par chimere.par.test.offline -todo f -startdate 2017010100 -hours 24 -restart yes -compil devel
    3. Run the model with the following command line to store the output on screen:
      ./chimere.sh -par ${parfile} -todo f -startdate ${curdate} -hours ${nh} -compil ${typmod} -restart ${chimrestart} 2>&1 | tee chimere_logfile.txt || exit 1
  2. Send the following files to the developers:
    chimere_logfile.txt
    compilogs/checkConfig.log
    compilogs/make.[num_of_compil].log
    src/mychimere.sh

Scientific Committee

Model Code Contributors

Some developments are performed in collaboration with several colleagues (researchers, PhD students, and post-docs):

  • Lya Lugon, CEREA, aerosols chemistry
  • Florian Couvidat, INERIS, aerosols chemistry
  • Paolo Tuccella, aerosols direct and indirect effects
  • Jean-Louis Monge, IR CNRS, code development, parallelization, until 2007
  • Dmitry Khvorostyanov, IR CNRS, code distribution and development, from 2007 to 2017
  • Nadege Blond (LIV/CNRS): urban pollution and data assimilation
  • Isabelle Pison (LSCE): Inverse modelling
  • Gilles Forêt (LISA): Data assimilation
  • Eric Chaxel: WRF meteorology interface
  • Gabriele Curci (CETEMPS - L'Aquila): Biogenic emissions
  • Alma Hodzic, NCAR, Boulder, aerosols chemistry
  • Cécile Honoré (Airparif): emissions, PREVAIR implementation
  • Frederik Meleux (INERIS): PREV'AIR
  • Robert Vautard and Matthias Beekmann (DR CNRS): designed the first model versions

Data Contributors

The CHIMERE model uses a lot of data kindly produced by colleagues. They correspond mainly to input data, boundary conditions. They agree to put their data on this web site for all users, and we acknowledge them for this open view of research:

  • The roughness length for mineral dust emissions comes from the GARLAP dataset, described in [Prigent et al., 2012] and is provided by Catherine Prigent. For use of these data in your publication, please add the following sentence:
    Comparison of satellite microwave backscattering (ASCAT) and visible/near-infrared reflectances (PARASOL) for the estimation of aeolian aerodynamic roughness length in arid and semi-arid regions by [Prigent et al., 2012, Atmos. Meas. Tech.].
  • Surface anthropogenic emissions suite. Data are provided by:
    EMEP, EDGAR, CAMS Global/regional anthropogenic emissions
  • The gaseous species boundary conditions: data are provided by Didier Hauglustaine and Sophie Szopa (Institut Pierre-Simon Laplace / LSCE) using the LMDz-INCA model (see http://inca.lsce.ipsl.fr/)
  • The aerosol species boundary conditions: data are provided by Mian Chin (NASA) from monthly means calculated with the GOCART model (Ginoux et al., 2001, 2004, JGR)
  • The landuse data: USGS and GlobCover
  • The LAI from NASA/EOSDIS: [Yuan et al., 2011] and COPERNICUS: [Fuster et al., 2020]
  • The biogenic emissions factor: [Sindelarova et al., 2014]
  • The DMS sea surface concentrations: [Lana et al., 2011]
  • The CAMS Global Fire Assimilation System (GFAS) assimilates fire radiative power (FRP) [Kaiser et al., 2012]
