Feb 1, 2025February 2025 — UMEP-dev/SUEWS: Implemented emissions method updates and default alignment to support multiple emission scenarios. Refactored model.py to update the EmissionsMethod enum and align the default emissions method in ModelPhysics, enabling accurate scenario representation. Two commits covered: c6a62428488857043f49a715c6974d81145f3b8b and ef09e48e8675126a51845269e45bcd42d9bafbde. No major bugs fixed this month. Overall impact: improved modeling fidelity, reduced configuration errors, and clearer code paths for extending emission scenarios. Technologies/skills demonstrated: Python enums, refactoring, model design for scenario planning, git-based change traceability.
