PROFILE
Andrew Nolan
Andrew Nolan contributed to the E3SM-Project/E3SM repository by enhancing the integration and reliability of the WW3 model within the E3SM codebase. He modernized the build system using CMake and Fortran, introducing conditional source file gathering and dedicated scripting to improve modularity and prevent misconfigurations. Andrew also aligned NetCDF-enabled components by refining build paths and names, and removed obsolete Fortran routines to streamline maintenance. His work included synchronizing the WW3 submodule with external updates, ensuring reproducible builds and clear traceability. These efforts demonstrated depth in build system configuration, code refactoring, and cross-repository collaboration, resulting in more maintainable and reliable workflows.

Feb 1, 2025February 2025 monthly summary for E3SM: Implemented WW3 Build System Integration to enhance integration accuracy and modularity of WW3 support in the E3SM codebase. Core changes include conditional gathering of WW3 source files in the CMake build, a dedicated WW3 sources script, and compile definitions to support WW3 components, with executables for WW3 grid and shell components. This work reduces build misconfigurations, accelerates WW3-enabled workflows, and establishes a scalable foundation for future WW3-related enhancements. Commit reference 4699c71bbdb9851426e18dcbde6b63aa739226a6.
