In April 2022, Oikuyajolu enhanced the E3SM-Project/E3SM repository by developing a feature that improved ocean-atmosphere flux modeling through the integration of Charnock parameterization and atmosphere-wave coupling. Using Fortran and leveraging expertise in numerical modeling and scientific computing, Oikuyajolu implemented the Charnock sea state parameter within the shr_flux_mod module, refactored subroutines, and introduced new parameters to support more accurate wave-stress accounting. This work enabled the coupling of atmospheric and wave components, allowing for integrated flux calculations and improved surface flux predictions. The update addressed model fidelity, supporting more reliable climate forecasts through deeper cross-component data handling.
