Q: Who can apply? 

The program is open to everyone. If you are interested in learning and working with ECMWF’s software and data, you can have a look at the challenges on GitHub and submit a proposal to the challenge you are most interested in. 

 You can apply as an individual or as a team. If you are applying as a team, we ask that one team member registers with a personal email and you indicate the other team members in the registration form.  


Q: How can I apply? 

 Go to the registration website. Here you are asked to follow several steps: fill your personal details in the registration form and upload your proposal into Submit new abstracts.


Q: Where is it? 

It is an online program, so you can take part from anywhere in the world. 


Q: What project would I work on?  

Possible projects that you can work on will be published on GitHub. The idea is that you can ask clarifying questions and this might be also useful for others interested in the challenge. 


Q: What is the selection process?  

The submitted proposals will be evaluated by a committee based on the following criteria: 

  • Feasibility

  • Innovative approach

  • Transferability

  • Easy to maintain / Future-proof approach

  • Comprehensibility

The programme committee can give your proposal in each category up to five points. The proposals with the highest overall number will be selected.  


Q: What will I get out of this? 

There are many reasons to get in involved in the ECMWF Summer of Weather Code program. It is a great opportunity for you to meet weather experts and showcase your skills in front of professionals in the industry. Teams selected for project developments will receive a £5,000 stipend. 


Q: How many participants will be selected?  

Five projects will be funded. You can submit a proposal either as individual or as a team.
