Worked on the UMEP-dev/SUEWS repository to enhance atmospheric and urban canopy modeling, focusing on stability, physical realism, and data integrity. Delivered features such as refined atmospheric stability calculations, improved betaN2 and blending height algorithms, and integration of new urban canopy parameters. Addressed edge cases and ensured non-physical results were prevented through careful code refactoring and parameter tuning. Used Fortran and Python to implement numerical methods, update test data, and resolve code conflicts, resulting in more robust simulations and reliable outputs. Maintained clear documentation and code cleanliness, supporting ongoing model development and alignment with urban environmental simulation standards.
February 2025 monthly summary for UMEP-dev/SUEWS focused on delivering higher-fidelity urban canopy modeling and stable data workflows. Key enhancements were designed to improve model accuracy and alignment with urban planning tools while ensuring test data remains representative of the current model expectations.
