How to contact the developers?
You can contact the developers, if you have questions about compilation, databases, parameterizations etc.:
chimere @ lmd.polytechnique.fr.

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. To do so you need to
    1. add --devel at the end of the compilation command line, for example :
      2. ./build-chimere.sh --no-oasis --devel
    2. add --devel at the end of the execution command line :
      3. ./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:
      4. ./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:
    3. chimere_logfile.txt
compilogs/checkConfig.log
compilogs/make.[num_of_compil].log
src/mychimere.sh
How to communicate with other users?
For any discussion about the chimere use, you can exchange informations with the other users by sending a message to the users mailing list: chimere-users@listes.lmd.ipsl.fr. Your registration of the registration page automatically add your e-mail adress to the chimere-users mailing list.

  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]
