Registration is now open for the 2nd Workshop on Correctness and Reproducibility for Earth System Software. This workshop will be held in conjunction with the Tutorial: Rigor and Reasoning in Scientific Software (R3Sw) and will take place November 5-7, 2025 at NCAR’s Mesa Laboratory in Boulder, Colorado and virtually. The R3Sw Tutorial runs primarily on Day 1 (Nov 5), with optional sessions on Days 2–3.
This workshop aims to provide a venue to discuss challenges, opportunities, and recent advances in ensuring software correctness and reproducibility for climate and weather modelers, HPC community members, and industry partners. The hands-on tutorial will cover core topics such as unit testing, continuous integration (CI), property-based testing, software design for testability, and reasoning in research software. (Note that we will offer travel support for a limited number of students and early-career researchers interested in the tutorial.)
See the event website for more information, including the tentative program for the complete 3-day schedule that includes tutorial sessions, panel discussion, invited and contributed talks.
Please register by October 20, 2025 for in-person registration ($80) or October 31, 2023 for virtual registration ($25).
This event is sponsored by the 2025 Better Scientific Software (BSSw) Fellowship program.
