Programme

Full programme will be announced soon

Join us to:

Apply AI to Climate Extremes Use AI tools and methods to model, monitor, and predict extreme weather and climate events in real-world scenarios.
Understand and Explain Models Learn how to make AI models more transparent, physics-informed, and causally grounded to improve trust and understanding.
Assess and Communicate Results Develop skills to interpret results and communicate findings effectively to scientists, decision-makers, stakeholders, and the public.
Collaborate and Exchange Ideas Work with experts in AI and climate science and connect with other researchers from different backgrounds.

Key Pillars

The foundation of all analyses, focused on the detection, harmonization, and integration of diverse data sources, from in-situ measurements and remote sensing observations to derived products, to ensure accuracy, consistency, and reliability across applications.

Development of models for monitoring, forecasting, and impact assessment across spatial and temporal scales, combining physical principles with statistical and machine learning methods to capture complex Earth system dynamics and improve predictive performance.

Advancement of explainability, causal reasoning, and attribution to identify drivers of change and assess impacts, combined with uncertainty quantification and robustness analysis to ensure transparent and reliable outcomes.

Bridge between science and action, using AI tools such as large language models and digital twins to support operationalization, policy development, informed decision-making, and responsible risk communication.

FAQs

Please beware of companies who may contact you offering to sell you a travel package (e.g. GT Reservations, GT Travel Expert, Converiatravels.). They are not endorsed by the ELLIS Winter School and we are not collaborating with them.

Also beware of hotel booking companies who contact participants claiming to be either a preferred supplier or, in some cases, working for our event, demand up-front payment, charge substantial penalties for changes and cancellation and may not even make a reservation with the unapproved hotel. You should always read the small print.

We advise that you make your travel and accommodation arrangements through reputable suppliers and not via unsolicited phone calls or emails. We will also send successful participants recommended airlines/flights and hotels.

Eligibility criteria (e.g. level of study, background, required documents) are described in detail in “Who is it for” section and can be accessed directly by clicking here. Please make sure to review this before submitting your application.

We are prioritizing in person attendance, but there may be some lectures that will be streamed. Please stay tuned to our website and email updates.

The registration fee is 350 EUR.
Please note that this does not include your travel to Athens or your accommodation during the Winter School.

Coffee breaks, snacks and lunch are covered. We will also cover a music evening social event. Registration fees, accommodation and travel costs are not covered by the school but there may be scholarships provided. Although we aim to secure funding for financial support for participants, it will be on a needs-basis. If financial support to cover registration fees and/or travel expenses becomes available, it will be offered to a limited number of participants prioritizing diversity and inclusion, promoting balance in discipline, gender, and geography, with a focus on applicants from low-income or widening countries. We look forward to supporting you to join this exciting career advancement opportunity in Athens, Greece!

Decisions on financial assistance (such as partial funding or fee waivers) will be communicated shortly after your application result. If you are accepted, your admission email will specify whether you have been awarded financial support and what it covers.

Applicants will be notified of the outcome of their application in early January 2026, via email.

There may be recommended preliminary readings, especially for the group work components. Details and materials will be shared with accepted participants in advance.

You will receive a certificate of completion, which you can include in your CV. Please note that it does not count as university course credits (ECTS or equivalent).

We plan to record only the lectures and zero to hero tutorials and share them with participants after the Winter School.
We may also do some light filming during the school (e.g. a short vlog/video recap of the event) for outreach and communication purposes.
