Output files

LMDZ-SACS output files are all saved in NetCDF format (execpt trajectory files which are save in raw binary format for I/O speed).

Log file

• dispersion.log: log file created by CIF, containing information about the simulation, and eventual error messages

Observation file

• obs_out.nc: observation information, for forward and tangent linear only

  • spec variable: simulated mixing ratio in :math:`mu`mol/mol (ppm)

  • incr variable: simulated mixing ratio increments in :math:`mu`mol/mol (ppm)

  • pressure variable: simulated pressure at the middle of the cell (Pa)

  • dpressure variable: simulated pressure thickness of the cell (Pa)

  • airm variable: dry air density (molec/cm³)

  • hlay variable: level thickness (m)

Tracers related fields files

Initial conditions files

• restart.nc: mass mixing ratio for all tracers at the end of the simulation, in kg of species per kg of dry air.

  • [species] (lev, lat, lon) or (lev, cell) variable: mass mixing ratio, for forward and tangent linear only

  • [species]_tl (lev, lat, lon) or (lev, cell) variable: mass mixing ratio, for tangent linear only

  • [species] (lev, lat, lon) or (lev, cell) variable: mass mixing ratio sensitivity, for adjoint only

Emissions files

• flux_out.nc: tracers surface emissions sensitivities

  • [species] (time, lat, lon) or (time, cell) variable: emissions sensitivities, for adjoint only
