Report on the 2023 Workshop on Correctness and Reproducibility for Climate and Weather Software

This collaborative event brought together the NCAR applications community with the broader HPC community, including potential industry partners, to address the practical challenges faced by climate and weather model applications regarding correctness and reproducibility.

The purpose of this report is to summarize the workshop and plan a path forward for future work, collaboration, and potential funding sources to take steps and advance towards the goals identified in the workshop. To this end, we discuss the motivation for the workshop, summarize presentations and discussions from the workshop sessions, and identify the critical issues and key takeaways, providing a roadmap for future work and collaboration.
