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.
