Output files#
Most of the output files are netcdf. Some choices are available to manage them.
dumpnctype#
The precision of the float in the output files. Called NetCDF_outtype in CHIMERE.
dumpncoutput#
Choice to dump or not concentrations in out.nc. Called NetCDF_output in CHIMERE.
dumpncpar#
Choice to dump or not various variables in par.nc. Called NetCDF_parout in CHIMERE.
nparammax:#
Maximum number of miscellaneous variables to be written in par.nc. Experienced users can increase it to add more parameters (see iniparams, outprint
).
Deposition output#
If required, the dry and wet depositions are written, cumulated every nsavedepos hours, in dep.nc. This file is in the following the format with NH, NZONAL, NMERID, NVERTI and NS given the relevant values, NDEPOS the total number of species to be deposited (counts two for a species that is both dry and wet deposited), NDEPDRY/WET the number of dry/wet deposited species:

Concentration field output#
If required, the 4D concentration fields are written at an hourly resolution. The values written are the concentrations obtained at the end of the specified hour i.e. they are not the average over this hour. This file is in the following the format with PP, NZONAL, NMERID, NIVOUT and NVERTI given the relevant values, NS the total number of species to write with their UNITS (default is ppb vol) and reference (WD = dry or wet) as indicated in OUTPUT_SPECIES.

Ouput of miscellaneous variables#
If required, a list of variables other than the concentrations are written in par.nc. This file is in the following the format with PP, NZONAL and NMERID given the relevant values, the list of parameters can be modified by experienced users in iniparams
and outprint
, increasing nparammax if necessary:
