Before creating the experiment, we first need to create the initial data. If you plan to rerun the ob00 or clim experiments and use the initial data 'as-is' you can skip this step.
...
Choose a starting date from the range 1st Nov to 15th Nov (00Z)
Make a copy of the ob00 data to your /scratch directory:
| Code Block | ||||
|---|---|---|---|---|
| ||||
cd scratch # starting from your home directory mkdir -p inidir/ob01 # our inidir # put all your personal initial data in here cd inidir mkdir ob01 # your new experiment id cd inidir/ob01 cp -rL /perm/rd/openifs/oifs_workshop_2017/expts-inidata/ob00/2015110100 . # those last characters are a 'space' and then a 'fullstop', '.' means "here". |
...
Ignore any errors about files not being copies copied because of permission problems.
| Code Block | ||||
|---|---|---|---|---|
| ||||
cd inidir/ob01 cp -rL /perm/rd/openifs/oifs_workshop_2017/expts-inidata/ob00/2015110[1-5]* . |
Please only copy the initial dates you intend to use. Each date uses 0.5 Gbyte of file storage.

cd inidir/ob01 cp -rL /perm/rd/openifs/oifs_workshop_2017/expts-inidata/ob00/2015112015110[1-3]* . # this will take besome slow!time. |
Change experiment id
OpenIFS forecasts are identified by an 'experiment id', a four letter string.
An experiment could consist of a single forecast date or multiple starting dates. It can be of any length and could also include a restarted forecast. However, an experiment only has one horizontal and vertical resolution.

|---|
It might help to put a README file in the experiment directory to remember what the aim of each experiment is. |
If you are using multiple dates, remember to change the experiment id for each date.
Initial files
The initial files containing 2D and 3D fields to start the forecast are contained in file that beging begin with ICM* : ICMGG* are the initial gridpoint files, ICMSH* are the initial spectral fields. ICMCL* is the file containing the climatological forcing fields.
