LMDz-SACS is coded in fortran. LMDz-SACS's sources for use by the CIF are made available in directory :bash:`/model_sources/DISPERSION_gch/`, which contains the relevant makefile and a compilation script. The actual .F90 sources are in the various sub-directories in :bash:`libf`. 

LMDz-SACS deals with time at a monthly resolution: all input and output files are for one month. Links can (and must) be used e.g. for emissions which do not vary through the year.

LMDz-SACS reads and writes netcdf and text files. 


The required inputs for the executable are:

  - text file :doc:`totinput<totinput>`: contains the main simulation parameters chosen by the user or deduced from these choices. Generated by pre-processor params.py included in the model's plugin.
  - :doc:`infousedsat.txt<infousedsat>`: contains information on the satellites used
  - netcdf file :doc:`defstoke.nc<defstoke>`: contains information on the on-line model
  - netcdf files :doc:`fluxstoke.nc<fstoke>`, :doc:`fluxstokev.nc<fstokev>` and :doc:`phystoke.nc<pstoke>`: contain the pre-computed mass fluxes
  - :doc:`vcoord.nc<coordfiles>`: contains the horizontal and vertical coordinates of the grid
  - :doc:`mod_SPEC.bin<emissions>` contain the emissions of species SPEC
