☀️ 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.

❗ Why "Copy-Paste" Fails in Science: Calibrating the Model for Calgary

🛰️ I’ve recently updated the land cover data for Calgary using my Proprietary MDEM Framework (Multi-dimensional Environmental Matrix).
Here’s an interesting technical challenge: the methodology that worked flawlessly on data from Kryvyi Rih, Ukraine, required significant recalibration for Alberta. Spectral signatures of Canadian spruce and local soil compositions are worlds apart from Eastern European environments.

💻 I am currently refining the local training set to ensure precise differentiation between vegetation types. This level of accuracy is vital for effective urban monitoring and improving the quality of life in our communities.

🌲 The preliminary classification results already offer a fresh, data-driven perspective on the city’s structure. The work continues!

@glv @mfowler Understood and appreciate that notion. Nonetheless ’should hold’ is not ‘shall hold’. I contributed to writing #APEGA ‘Guideline for professional responsibilities in developing software’ back in 2006. It is flawed but also emphasized being “primarily concerned with their responsibility for minimizing risk of failure and protecting the public interest” Could something similar be created in your jurisdiction or beyond?
