OpenIFS provides academic and research institutions with an easy-to-use version of the ECMWF IFS (Integrated Forecasting System). OpenIFS provides the forecast capability of IFS (no data assimilation), supporting software and documentation. OpenIFS has a support team at ECMWF for technical assistance but limited resources for detailed scientific assistance.

About OpenIFS provides more information about the model.


How to run openIFS:


First check openifs availability on your platform. Currently openIFS is available on UIO HPC (abel.uio.no) only. 

module avail openifs

-------------------------------------------------------------------------------- /cluster/etc/modulefiles ---------------------------------------------------------------------------------
openifs/38r1v04(default)


If nothing is returned, it is likely openifs is not available. If you think it should, then contact us (drift@uio.no).

To load the default openifs version: 

module load openifs


When loading openifs the following environment variables are defined:

  • OIFS_CYCLE: ECMWF cycle such as 38r1 (version 38, revision 1)
  • OIFS_HOME: directory where openIFS has been installed; this can be used to check openIFS sources
  • OIFS_DATA: contains openIFS static input data. Even if you use your own compiled version of openIFS, it is NOT necessary to download these files again.
  • OIFS_EXAMPLES: directory where all openIFS examples are stored. If you wish to run one of these examples see our dedicated section on running tutorials.
  • OIFS_COMP: compilers used to create openIFS executables. We currently use intel compilers.
  • OIFS_BUILD: type of build. It triggers a set of compiler options when building openIFS. Currently set to "opt"
  • OIFS_GRIB_API_DIR: GRIB-API version used by openIFS to encode/decode GRIB files
  • MARS_LSM_PATH: land sea mask used
  • EMOS_VERSION: EMOS version (compiled with GRIB-API support). EMOS is used for interpolation routines.
  • EMOS_HOME: directory where EMOS has been installed.
  • BUFR_TABLES: bufrtables used for decoding/encoding BUFR (not used in the forecast model)
  • CREX_TABLES: crex tables used for encoding/decoding CREX data.
