Register now for the 2nd Workshop on Correctness and Reproducibility for Earth System Software

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 24, 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.
