EMI R&D projects application

European Meteorological Infrastructure Research and Development Projects (EMI R&D Projects), formerly known as Special Projects, are defined as 'experiments or investigations of a scientific or technical nature, undertaken by one or more Member States, Co-Operating States, EUMETSAT or EUMETNET, likely to be of interest to the general scientific community'.

Users within one of ECMWF's Member or Cooperating States and European Meteorological Infrastructure (EMI) entities may apply for resources as an EMI R&D Project. This possibility is particularly, but not exclusively, suitable for projects which are undertaken in co-operation between several institutions, nationally or internationally. The decision to treat a project request as an EMI R&D Project application is made ultimately ECMWF's Scientific Advisory Committee (SAC) and Technical Advisory Committee (TAC), after the internal ECMWF review.

European organisations with which ECMWF has concluded Co-operation Agreements may apply for resources for an EMI R&D Project, such a request to be considered by the Director-General of ECMWF as well.

To get an idea of the kind of research which has been approved as EMI R&D Project, please refer to the table of active EMI R&D Projects.

Computing resources available to EMI R&D Projects

The allocation of computing resources is decided by the ECMWF Council. The Council guidelines on distribution of computer resources  currently state that an equivalent of 10% of the computing resources available to Member States may be allocated to EMI R&D Projects. 20% of that 10% is set aside as a reserve for allocation by ECMWF directly either to late applicants or to projects which have exhausted their allocation before the end of the year.

Resources available in 2026

The operational HPC service will be provided by the ECMWF HPCF. For more details please refer to our HPC user documentation. 

The resources available to EMI R&D Projects in 2026 are estimated as follows

Total resources

Reserve

Maximum per EMI R&D Projects per year

The amount of resources requested by each project for each year cannot exceed 8% of the total amount of resources available for that year.

The maximum amount of 308 million SBU is equivalent to about 16 million hours elapsed time for a serial job or e.g.  to running a parallel job on two nodes for about 63625 hours on the Atos HPC.

European Weather Cloud resources

EMI R&D Projects also have access to the operational European Weather Cloud service. This infrastructure delivers cloud-based processing capabilities and data access to serve a range of applications as illustrated by the presentations at the European Weather Cloud User Workshop. If you are interested in this service, please indicate your resource requirements and add a section outlining your intended usage to your EMI R&D Project request.

The total European Weather Cloud resources available to EMI R&D Projects are 

¹ The number of vGPUs refers to equivalent vGPU with 8 GB GPU memory. Please note that per virtual machine max. 1 vGPU will be allocated.

Maximum per EMI R&D Project per year

For the European Weather Cloud typical configurations would be allocated up to: 

Requests exceeding these resource limits can be discussed on a case-by-cases basis.  

For more information please visit the European Weather Cloud portal or the Knowledge Base.​

Estimating your resource requirements

HPCF System Billing Units (SBU) are currently based on the total elapsed time of physical CPUs used. For more information please refer to our HPC accounting documentation.

Your Computing Representative may be able to advise you on the amount of resources you should apply for or may suggest that you contact the ECMWF Service Desk for advice.

EMI R&D Projects - how to apply

Requests for an EMI R&D Project 2027-2029 should be submitted using the EMI R&D Project request submission web form, which will automatically forward your request to the relevant meteorological service for information and ECMWF EMI R&D Projects management team for the assessment. If possible, you should submit your request in good time.

All EMI R&D Project requests should provide an abstract/project description including a scientific plan, a justification of the computer resources requested and the technical characteristics of the code to be used. Requests asking for 10,000,000 SBUs or more should be more detailed (3-5 pages).

Submitted EMI R&D Project request will be evaluated by ECMWF and its Scientific and Technical Advisory Committees (SAC and TAC). The evaluation of the requests is based on their scientific and technical quality as well as the justification of the resources requested. Previous EMI R&D Project reports and the use of ECMWF software and data infrastructure will also be considered in the evaluation process.

For details of the procedure, see the "Guidelines for handling applications for computing resources for EMI R&D Projects".

If you miss the 30 June deadline, you should submit a "late request" as soon as you can: You may be eligible to receive resources from the 20% of EMI R&D Project resources which are set aside as a reserve specifically for ad hoc allocation. To submit a late request via your national meteorological service please use the web form provided. Please note that late requests will be limited to the following resource thresholds:  

Maximum for "late requests"

For all new EMI R&D Project requests please login to the ECMWF website and submit/upload your request via the EMI R&D Project request submission web form.

If you wish to make any changes to a previously agreed EMI R&D Project, you should send an updated request directly to ECMWF before 30 June. If you ask for more resources than initially allocated, the allocation granted will be subject to their availability and evaluation of your progress report.

Procedure for the handling of applications

To manage any possible oversubscription of computing resources available to EMI R&D Project, the following procedure for the handling of applications for computer time for EMI R&D Project has been agreed.

• Each project will have a well defined duration, up to a maximum of three years, agreed at the beginning of the project.
• The amount of resources requested by a single project for each year is limited to 8% of the total resources available in that year.
• To avoid accepted EMI R&D Project requests needing reduction by more than 20%, some EMI R&D Project requesting large amounts of computing resources may not be accepted.

Applying for additional resources for an existing project

Should you exhaust your resource allocation before the year's end, you can, at any time, apply for an allocation from any resources remaining in the reserve. Please note that a relatively large request for additional resources might trigger a more thorough evaluation of your project. To apply for additional resources, please use the form provided. Please note that requests for additional resources per year and project will be limited to the maximum size of a late EMI R&D Project request.

Progress and final reports

ECMWF expects to receive annual progress reports by 30 June each year (except for one-year projects) and a final report at the latest by 30 June in the year following the end of a EMI R&D Project. All reports will be published on the ECMWF website and taken into consideration by the Scientific Advisory Committee for the evaluation of any new EMI R&D Project application from a Principal Investigator or from members of the same project/working group.

Please submit your report via the EMI R&D Project report submission web form.
