Introduction

The WCRP Digital Earths Lighthouse Activity—supported by key initiatives like Destination Earth (DestinE), Next Generation Earth System Modelling (NextGEMS), WarmWorld, Earth Visualization Engines (EVE), European Eddy-Rich Earth System Models (EERIE), WCRP ESMO, and with the endorsement of the CMIP panel—is serving as the primary sponsor and coordinating body for this hackathon. The Hackathon will be based on output from 6-8 models simulating the annual cycle at sub 5 km resolution. The models adopt a common simulation protocol, namely the Sendai protocol.

The goals of the event are to:

  • Promote Global Collaboration, by sharing best-practice in process-based analysis of km-scale simulations: this hackathon will encourage global data sharing and collaborative workflows, allowing experts to work together on the analysis of “Storm Resolving Models” at both global and regional levels.

  • Enhance Accessibility: our focus is on making high-quality data resources readily available to users, with support from designated ambassadors who can facilitate international collaboration and access to key data nodes.

  • Expand Long-Term Access: looking ahead, the aim is to broaden access for a wider user base by applying the lessons learned from these early efforts to support a more connected data-sharing environment.

This hackathon offers a valuable opportunity for experts to collaborate, share insights, and help advance the development of earth system modeling tools and practices.

Expected outcomes

The 2025 global hackathon is designed to:

  • Foster Community and Open Access: Encourage a spirit of collaboration and ensure open access to resources, helping to strengthen connections across the community.

  • Promote and Share Best Practices in Coding and Data Workflows: Share effective practices for coding, infrastructure, and data-intensive applications to improve workflows and results.

  • Establish Common Standards: Support the development of shared standards for weather and climate data, ensuring consistency and reliability in storm-resolving research.

  • Drive Advances in Storm Resolving Models: Focus on enhancing and analyzing global and regional Storm Resolving Models for more trustworthy predictions.

Organization and Timeline

The 2025 WCRP Global KM Scale Hackathon is a distributed, collaborative event where nodes across the globe work together under the guidance of a steering committee and a technical group, both composed of node representatives, to develop standardized workflows.

Each node will be hosting O(100) scientists, working around a common set of weather&climate data and tools, as well as focussing on region-specific scientific challenges and approaches. The hackathon will broadcast results, discussions, etc. in real time, so that at any given time of the day one of the international nodes will be in charge.

A number of preparatory actions are in place, and technical, scientific and logistic meetings are held on a monthly basis. The Gantt chart shows the current set of actions for preparation, which are constantly updated.

Satellite Nodes

In addition to the regular hackathon nodes, several Affiliated Nodes will contribute to the kilometer-scale hackathon by hosting teams focused on special projects sponsored by NVIDIA, ESA, and Destination Earth. These nodes will enable targeted exploration of themes such as AI-enhanced analysis with NVIDIA, EarthCARE data utilization with ESA, and the use of DestinE datasets with ECMWF. While the analyses are not pre-defined, all projects will benefit from shared hierarchical data grids and new lightweight analysis frameworks, allowing researchers—including those bringing their own scientific questions—to rapidly prototype and collaborate.

Program and protocol

This is the general schedule that should allow most participants to travel on Monday and Friday

  • Monday afternoon to Friday morning

  • Monday afternoon: welcome, theme updates, general information

  • Friday afternoon: work group roundup, general discussion of future steps for the project

  • Tuesday to Thursday: group work

  • General discussions and updates on daily highlights across nodes (modalities TBD)

  • Each node will decide on how to structure the week work

Here is a very general draft agenda.
