Directory structure and file names:


On this server, the structure of the directories is the following:

 Exp_type1/ (e.g. PIcntrl, 20C3M, Commit...)
 A1/ Monthly atmospheric data (A1a, A1b, A1c, A1d, A1e IPCC tables)
 Ensemble_member_1/
 Ensemble_member_2/
 ...
 A2/ Daily atmospheric data (A2a, A2b IPCC table)
 Ensemble_member_1/
 Ensemble_member_2/
 ...
 A3/ 3-hourly atmospheric data (A3 IPCC table)
 Ensemble_member_1/
 Ensemble_member_2/
 ...
 A4/ Extremes (A4 IPCC table)
 Ensemble_member_1/
 Ensemble_member_2/
 ...
 O1/ Ocean data (O1a, O1b, O1c, O1d, O1e, O1f, O1g IPCC tables)
 Ensemble_member_1/
 Ensemble_member_2/
 ...
 Exp_type2/
 ...

 (For the time being, every IPCC-type experiment contains only one member)
 
 Example: you need ocean meridional overturning streamfunction for control experiment (preindustrial) CT1
 - by a quick look at tables included in "IPCC Standard Output from Coupled Ocean-Atmosphere GCMs" (that you have printed !), you see that this variable (CF standard name "ocean_meridional_overturning_streamfunction", short name "stfmmc" is in table O1b. 
 - so go to directory /Datasets/Simulations/Coupled/CNRM-CM3/PIcntrl/O1/CT1
 - the relevant .nc files always contain the short name of the needed variable in their names. Except for 3-hourly data, the fields are always stored by chunks of 10 years. We followed this IPCC recommendation, even if some daily-3D data files are very bulky (up to 1 Go !). If this is definitely too much we may have to split these files to 1-year files.

 - file names are defined as follows:

 [Field_short_name]_[Data_category]_[First_year]-[Last_year].nc
 
 with:
 Field_short_name = the needed variable's short name (see "IPCC Standard Output from Coupled Ocean-Atmosphere GCMs" for a comprehensive list) 
 Data_category = A1, A2, A3, A4 or O1
 First_year, Last_year = first/last year of the time series 

 - in our example, the name for monthly ocean meridional overturning streamfunction between years 2050 and 2059 of CT1 control experiment will be: stfmmc_O1_2050-2059.nc

 - note there is no reference to experiment name in file name, but of course full information about how the experiment was designed is included in the .nc file as comments.
