Digital Earths Global Hackathon

Welcome

NSF NCAR will host the US-Central “node” of the World Climate Research Programme (WCRP) Digital Earths Global Hackathon, a globally distributed event designed to advance the analysis and development of high-resolution Earth-system models.

This 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. The US-Central node will be hosted at the NSF NCAR Mesa Laboratory in Boulder, Colorado.

Registration information for the NCAR node and other information specific to the event taking place at NCAR is found below. For more details about the global hackathon and its objectives, please visit the official WCRP event page.

Registration

Registration for the NSF NCAR Node of the Digital Earths Global Hackathon is not yet open. A link to the registration page will be published here once it becomes available.

In the meantime, if you’re interested in participating, you can express your interest in joining this or another U.S. node of the Global Hackathon via this page. Stay tuned for updates as the event approaches!

Travel support

The organizers are exploring options to offer travel support specifically for early-career researchers to encourage their participation in the NCAR Node of the Digital Earths Global Hackathon. If your ability to participate depends on receiving travel assistance, please visit the current registration page and fill out the relevant section to indicate your need.

Program

The NCAR Node of the Digital Earths Global Hackathon will run from Monday afternoon, May 12, to Friday lunchtime, May 16, 2025.

A detailed day-by-day program will be shared closer to the event.

NSF NCAR node data sets

A description of the data sets contributed by and hosted by NSF NCAR follows. NCAR will also provide local access to select shared data sets provided by the global event organizers.

• MPAS DYAMOND Phase 3 simulation - A 1-year simulation with MPAS-A at 3.75km global grid spacing. (Additional details to be provided.)
• (Tentative) CONUS404 - Regional climate simulation over contiguous USA using WRF at 4km grid spacing.
• (Tentative) SAAG - Regional climate simulation over South America using WRF at 4km grid spacing. (additional details)
