CELLO - Climate Exploration in Lively Liaison with the Ocean | 5th International Conference on Earth Modeling

Bucerius Law School in Hamburg

CELLO brings together international experts in ocean turbulence, air-sea-ice interactions, and computational methods to model and better understand ocean dynamics. The meeting will take place from September 16th to 18th, 2025, at Bucerius Law School in Hamburg.

Nearly 50 years ago, the Max Planck Institute for Meteorology, under the leadership of Klaus Hasselmann, recognized the ocean's crucial role in the climate system. Since then, advances in computational power and observational techniques have dramatically enhanced our ability to observe and simulate dynamics that were previously beyond our reach. These advancements now offer deeper insights into Earth's climate and its potential future changes, including how, where, and to what extent these changes might occur.

CELLO seeks to convene leading scientists from our field to share the latest research findings, explore future directions, and foster opportunities for collaboration.

To learn more about the conference themes and convenors please refer to the Conference Program. Submissions and registration will open on this website in Spring 2025.

Hamburg Node of the Digital Earths Global Hackathon

Bundesstr.53, 20146 Hamburg

The Hamburg Node of the Digital Earths Global Hackathon is part of the World Climate Research Programme (WCRP) Global km-Scale Hackathon, an initiative designed to advance the analysis and development of high-resolution Earth-system models.

The Hamburg event, taking place from May 12 to 16, 2025, will gather participants to collaborate on hacking, bug-fixing, and learning in a dynamic, hands-on environment. This hackathon is part of the larger WCRP effort to push the boundaries of climate system modeling and digital innovation globally.

For more details about the global hackathon and its objectives, please visit the official WCRP event page.

Registration closes on April 21, 2025 and a registration fee of 150€ is asked. Quicklink to external registration website

KlimaCampus Colloquium: The technology deleting photobombs can do climate research? The chat bot writing poems can do climate analysis?

Bundesstrasse 53, room 022/23 ground floor

Climate change research today relies on climate information from the past. Historical climate records of temperature observations form global gridded datasets that are examined, for example, in IPCC reports. However, the datasets combining measurement records are sparse in the past. Even today, they contain missing values. We found that recently successful image inpainting technologies, such as those found on smartphones to get rid of unwanted objects or people in photos, are useful here. The derived AI networks are able to reconstruct artificially cropped versions in the grid space for any given month using the missing values observation mask. So herewith we have found with AI a technique that gives us data from the past that we never measured with instruments.  Other important datasets used in the Assessment Report 6 of the IPCC to study climate change, as well as advanced applications such as downscaling in atmosphere and ocean, a hybrid (AI&ESM) data assimilation approach within ICON, or precipitation in broken radar fields are shown in this presentation.

Climate research, including the study mentioned in the previous paragraph, often requires substantial technical expertise. This involves managing data standards, various file formats, software engineering, and high-performance computing. Translating scientific questions into code that can answer them demands significant effort. The question is, why? Data analysis platforms like Freva (Kadow et al. 2021, e.g., gems.dkrz.de) aim to enhance user convenience, yet programming expertise is still required. In this context, we introduce a large language model setup and chat bot interface based on GPT-4/ChatGPT, which enables climate analysis without technical obstacles, including language barriers. This approach is tailored to the needs of the broader climate community, which deals with massive data sets from kilometer-scale modeling and requires a processing environment utilizing modern technologies, but addressing society after all - such as those in the Earth Virtualization Engines (EVE eve4climate.org).
