Ingredients to make a reproducibility test of EC-Earth 3.2 and later.
Largely based on Paolo Davini's initial scripts to make a climate assessment of EC-Earth

Current limitations and constraints:
* The output must come from EC-Earth 3.2.2 or later. Otherwise, variable names
  might need some changes
* The output must be available as MMO, MMA tar files and ICMGG, ICMSH grib files
* The output must consist in 12 month data per file
* The simulation must start with January and finish with December 

1/ Checkout the git project from the BSC archive
------------------------------------------------
>> git clone https://earth.bsc.es/gitlab/fmassonnet/reproducibility.git
>> git checkout master

2/ Edit the configuration file
------------------------------
>> vi ./scripts/config.sh

3/ Pre-process the EC-Earth output
----------------------------------
>> cd ./scripts
>> ./preprocess.sh ${exp} ${memb} ${yearb} ${yeare}

[ Execute ./preprocess.sh to see the help ]

Process *all* your members of all experiments. This can be done in parallel
by using nohup commands for instance.

4/ Re-grid to the same grid as the observational reference
----------------------------------------------------------
>> ./postprocess.sh ${exp} ${memb} ${yearb} ${yeare}

5/ Compute the Reichler and Kim indices
---------------------------------------
./scores.sh ${exp} ${memb} ${yearb} ${yeare}

NetCDF files and a text file will be available in the directory EC-Earth_diags.
This text file (PI3.txt) consists in scores. By looking at how scores vary from
member to member one can guess if an experiment is reproducible wrt another one.

NOTE THAT STEPS 3/, 4/, 5/ can be clustered by using ./wrapper.sh

Once steps 1/ -> 5/ have been done for all members, we can proceed
to ensemble analyses:

6/ Ensemble analyses
--------------------
./ensemble.sh ${exp}
