️ Albedo vs. Surface Temperature: Why a "Bright" City Isn't Always Cooler
Key findings from the current stage of research:
Vegetation (NDVI): Based on modeling results, biomass health accounted for approximately 40% of the variance in Calgary’s temperature regime in 2025. Albedo (Reflectance): While it is commonly assumed that high surface reflectance reduces heat absorption, satellite data (broadband shortwave albedo) reveals a far more nuanced picture.
The Seton Anomaly
The scatter plot clearly shows a wide distribution of values. The community of Seton is a particularly striking example: despite its high average albedo (likely due to light-colored soils at construction sites and new roofing materials), the area remains in a "heat zone" (classified as Warm Background in my model). Albedo plays a role, but it is not the dominant factor in Calgary’s environment.#Calgary #UrbanHeat #DataScience #ClimateResilience #YYC #Geoscience #CityPlanning #RemoteSensing #RStats #APEGA #GreennesOfCalgary

@datastory Albedo’s not the silver bullet here.
