Impacts of Urban Green Infrastructure on Extreme Events in Cities
A Multi-City Digital Twin Study of the Role of Green Infrastructure in Coupled Land-Atmosphere Prediction
• Developed Noah-MP HUE —the first urban land surface model with sub-grid lateral water transfer and GI heterogeneity
• Urban vegetation in Milwaukee reduced simulated land surface temperatures by 5–15% in heavily impervious areas
• Nocturnal urban heat island reduced by ~2% and precipitation patterns improved vs. in-situ observations
• Large-scale greening reduces summer runoff and lowers daytime heat index on extreme heat days (≥90°F)
• Noah-MP HUE is coupled with WRF, enabling city-scale digital twin simulations of GI adaptation scenarios
