Terminology
The CPDN OpenIFS@Home uses slightly different terminology to what OpenIFS users might be used to.
OpenIFS@Home Ancillary Files
This refers to all the input files that the OpenIFS model needs to run:
- initial data to start a forecast (normally obtained from ECMWF);
- ifsdata and climate files (downloaded from the OpenIFS ftp site);
- model namelist (only parts of the OpenIFS namelist can be uploaded, see below)
These ancillary files are stored in a zipped format on the CPDN repository.
Experiment information is read from the initial files GRIB metadata upon upload to the OpenIFS@Home repository and used to set the experiment id, date/time of forecast etc.
