All model "data" output is written in RPN standard files.
There are different types of data the model can output:
| Sommaire |
|---|
- "normal" 2-D and 3-D output
- Time series (station data)
- Zonal means (rarely used)
- Pilot files
- Analysis files
Click on the following link for a description of the most common variables: variable dictionaries
The model will also save these other files:
...
...
All files above are stored in 'machine:directory' as specified by 'CLIMAT_arch_mach' and 'CLIMAT_archdir' in the file 'configexp.cfg'.
The files are organized into the following subdirectories:
| Samples | Raw n-hourly/minutely model output |
| Diagnostics | Monthly means , and variances, and timeseries calculated/assembled by the post processing (only if CLIMAT_diagnos=1 ) "normal" output used for evaluation/analysis |
| Analysis | Initial conditions files which can be used to initialize another simulations (only if CLIMAT_out_anal is set) |
| Pilots | Pilot files which can be used to drive another simulation at the lateral boundaries (only if CLIMAT_out_pilot is set) |
| Listings | Model listings, jobs, and config files |
| Restarts | Restart files which can be used to restart a simulation from given check points. Once a simulation is finished remove several of these files to only keep 1 or 2 per year, since they are fairly large. |
And then you should also have this file:
maingemdm_Linux_x86-64.Abs
or
maingemdm
which is a copy of the executable.

There are four types of output files:
| dm | dynamics on model levels |
| dp | dynamics on pressure levels |
| pm | physics on model levels |
| pp | physics on pressure levels |
...
Samples (direct model output
...
)
All fields requested in 'outcfg.out' are written into the four types of output files for the requested frequencies.
Diagnostics
If 'CLIMAT_diagnos=1' in 'configexp.cfg' the Diagnosticsmodel output will get further processed.
The diagnostics contain:
- monthly means and variances calculated for all model output fields
- 2-D time series for selected fields (if requested and available)
Fixed fields
Fixed fields can generally be found under the 'Samples' directory inside the directory ending on '*_step0'.
ME will be in the dm-file, all other fixed fields are usually in the pm-file.
Time series (station data)
In addition to the general 2-D and 3-D output, GEM/GEMCLIM can output time series at selected grid points (stations).
...
These files will get archive in the directory named "Pilots". They contain all fields needed to drive a simulation at the lateral boundaries.
Ancre Listings Listings

While the model is running the listings (log files) will appear under the directory:
~/listings/${TRUE_HOST}
There names will all start with ${GEM_exp}_* (as defined in your 'configexp.cfg').
Once a job/month finished properly they will all get archived under:
${CLIMAT_archdir}/Listings/listings_${GEM_exp}.zip
'CLIMAT_archdir' is also defined in your 'configexp.cfg'.
Actually, there are up to four zip files under ${CLIMAT_archdir}/Listings/listings_${GEM_exp}.zip:
| listings_*.zip | Contains all listings (log files) of finished simulations and their post processing |
| configs_*.zip | Contains a copy of all used config files (they get updated during a simulation |
| jobs_*.zip | Contains all model and post processing jobs which were created and ran |
| cjobs_*.zip | If Chunk_lance was used this file contains all "chunk" jobs |

At the end of each job, a restart file gets written. This contains the physics and dynamics files needed to restart the model. There will be files for each tile. These files contain a copy of the atmosphere and soil fields at the last time step of the job. When the next month gets started it reads the restart files of the previous month and continues from there. After the new month has started, the restart files from the previous month get archived on CLIMAT_arch_mach in CLIMAT_archdir as specified in your 'configexp.cfg'. It is always possible to restart the model at any given month from a restart file.
Since the restart files contain a full copy of the model atmosphere and soil they are quite large. So usually we do not keep all of them but erase some by hand afterwards. The name of a restart file looks like this:
${GEM_exp}_step###.tarz
With '###' being the number of the last timestep that was run.
