New release: OpenIFS40r1v2

OpenIFS 40r1 has been updated and a new version oifs40r1v2 is now available.

For more information, see Release Notes for OpenIFS 40r1v2.

The main modifications are as follows:

  • OpenIFS 40r1 is extended with an evaluation tool based on Metview macros. The new package makes it possible also to assess the meteorological performance of OpenIFS based on two sets of case studies. Input data, the Metview visualisation programs with detailed guidance and output figures are available for download. For further information please see the article in the latest Newsletter issue:
  • The semi-Lagrangian (SETTLS) scheme is modified for improved stratospheric warming forecasts and various improvements for the semi-Lagrangian interpolation and mass fixers.
  • OpenIFS modified to use ecCodes. As grib-api will not be supported after the end of 2018, we recommend users migrate to ecCodes.

Note OpenIFS 40r1v2 will not produce the same meteorological results as the previous releases 40r1 (40r1v1 and 40r1v1.1).

The OpenIFS team would like to acknowledge the research and support of ECMWF scientists involved in this release and the contribution of the OpenIFS users.

OpenIFS 40r1 close to retirement
This is the final release of OpenIFS 40r1, we will not be making any further updates to 40r1 versions. Depending on which versions of 40r1 users are working with, they are all still supported.

OpenIFS User Forums
We encourage users to post issues/questions/discussion on the OpenIFS User Forums. This ensures answers are available for all to see.  An ECMWF web account is required to post to the forums.

Simon McIntosh-Smith, Professor of High Performance Computing, Head of the HPC Research Group, University of Bristol, and PI for the Isambard project is working with OpenIFS to trial a new AMD based supercomputer for NWP and climate applications.


Position to be filled as soon as possible and latest on 1 January 2019.

University of Ljubljana in Ljubljana, Slovenia.

We are currently recruiting for a scientist to join OpenIFS.

For further details, please see the vacancy notice VN18-20 on the ECMWF jobs page:

Please note the deadline is 15th June 2018.

A updated version of OpenIFS 40r1v1 was released today, version 40r1v1.1.

This fixes a serious bug in the model where it would crash if restarts were generated when the wave model was enabled.

For more details, see the Release notes for Cycle 40r1v1.1

An article on the 2017 OpenIFS user workshop in Trieste has appeared in the Autumn issue (no. 153) of the ECMWF Newsletter.

ECMWF has recently launched a set of online e-learning modules, some of which are of interest for OpenIFS.

The modules are free, do not need a login, and are available here:

Modules include:

1. Parametrization of diabatic processes
2. Parametrization of diabatic processes: case studies
3. The mass flux approach and the Integrated Forecast System (IFS) scheme
4. Ensemble forecasting; an introduction
5. An introduction to single column modelling.
6. An introduction to the parametrization of sub-grid processes.
7. An introduction to Metview
8. An introduction to Metview for the single column model.

Some of the material in these courses is derived from ECMWF training courses.

Feedback on these courses is welcome.

New member of OpenIFS team

We welcome Gabriella Szepszo to the OpenIFS team. She joins ECMWF as a graduate trainee from the Hungarian Meteorological Service for 1 year initially. Whilst here she will work on improving the provision of idealized configurations of the OpenIFS model as well as other topics, and providing support.


For more information on the OpenIFS 2017 user workshop, see the ECMWF news item here:

The OpenIFS team invited back to ENM / MeteoFrance for 2017 to repeat the successful forecasting workshop of 2016, along with ENM lecturers Frederic Ferry and Etienne Chabot.
