Digital Earths – Global Hackathon
May 12-18 2025 – Beijing, Boulder, Oxford, Sao Paulo, Hamburg, Tokyo
The Digital Earths Global Hackathon will bring together scientists from around the world to jointly analyze the first ever coordinated experiments of climate models simulating a full annual cycle with horizontal grid spacings of 5 km or less).
Participants will gather at one of a number of regional nodes for the hacking, each of which will provide access to a combined data-compute resource hosting the data and proximate computing capbility for its analysis. Each node will host at least one full annual cycle of output data standardized on a common (HEALPix) grid. Standardization will help participants share their analysis workflows with other teams analyzing other models at other nodes, and thereby build global communities around common interests.
Goals
- accelerate the improvement and analysis of km-scale climate models (including regional models)
- socialize best practices in coding and data intensive applications (infrastructure and workflows)
- establish and disseminate the advantages of adopting common standards for km-scale climate information
- build solidarity and open access to resources
In addition individual centers may provide access to additional resources to supplement the standardized model outputs. This could include output from km-scale regional models or km-scale satellite data all of which would ideally be standardized similarly to the global models. Likewise computing capabilities could be augmented to support the application of machine learning.
Organization
A scientific steering committee will be responsible for the organization and will be supported by sub-committees for technical and logistical issues.
Participating teams around the world will assign someone to the sub-committees and is welcome to nominate a member for the scientific steering committee.
