Worked on the E3SM-Project/E3SM repository to enhance aerosol microphysics modeling by extending MODAL_AERO_5MODE support and improving coupling fidelity between microphysics and aerosol processes. Addressed key bugs in aerosol–microphysics and ice nucleation coupling, refining Fortran code to ensure accurate handling of sulfate, organic matter, black carbon, and secondary organic aerosols. Introduced tunable aerosol diameter thresholds in MAM5, adding new namelist options and variables for flexible scenario configuration. Updated API surfaces and documentation to improve usability and reproducibility. The work emphasized robust model configuration, code maintainability, and scientific computing best practices, supporting advanced atmospheric and climate modeling workflows.

4 Commits • 1 Features
May 1, 2025May 2025 focused on improving aerosol–microphysics coupling fidelity, configuration robustness, and code maintainability in the E3SM model. Delivered a set of bug fixes and an extension to support MODAL_AERO_5MODE across relevant code paths, targeting accurate coarse-mode aerosol processing, ice nucleation coupling, and rain-evaporation scenarios. The work reduces the risk of incorrect aerosol processing, improves cross-configuration consistency (MAM4/MAM5), and enables reliable experimentation with higher-mode configurations while maintaining backward compatibility.
