CHIMERE is coded in Fortran90.
CHIMERE’s sources for use by the CIF
(see how they differ from standard distributions here) are made available in directory
/model_sources/chimereGES/ which contains various subdirectories with actual
.F90 sources and relevant
Makefile, a compilation script and a header for all Makefile (makfile.hdr).
CHIMERE reads and writes netcdf and text files. The required inputs for the executable are:
text file chimere.nml: contains the parameters chosen by the user or deduced from these choices. Generated by pre-processor
params.pyincluded in the model’s plugin.
text file for the coordinates of the grid: COORDcorner
netcdf files for the initial and boundary conditions: INI_CONC.0.nc and BOUN_CONCS.nc
netcdf files for the emissions, AEMISSIONS and, if switched on, BEMISSIONS
netcdf files METEO for the meteorological variables
12 text files for the chemical scheme (some may be empty but they must exist)
text file LANDUSE if deposition is switched on
In case the model is run for comparison to observation data, a text file which contains the locations and times at which to extract simulated data is also read.
