During May 2025, Gn835658 focused on enhancing the reliability and accuracy of the SUEWS model within the UMEP-dev/SUEWS repository. They addressed a convergence issue in the Sensible Heat Flux iteration by refining the threshold logic and streamlining variable updates, which improved the stability and repeatability of simulation results. Their work involved careful code refactoring in Fortran, applying expertise in atmospheric physics and numerical simulation to standardize the handling of atmospheric stability parameters. This targeted bug fix reduced the risk of divergence in model runs and improved maintainability, laying a stronger foundation for future development and more robust forecasting.
