📈 Imperviousness vs. Temperature: Calgary's Primary Thermodynamic Trend

Mapping 313 Calgary communities reveals a linear relationship between % impervious surface area (Random Forest model on Summer 2025 Sentinel-1/2 & Landsat 8/9) and Land Surface Temperature (LST).

📊 Key Data Points:
• Cool Pole (<28°C, 0–15% impervious): Glenmore Park, Fish Creek (water & mature canopy).
• Hot Pole (37–40°C, 85–95% impervious): Industrial (Franklin, Foothills) & residential (Marlborough, Rundle).
• Thermal Slope: Every +10% impervious cover adds +1.2°C to +1.5°C to LST.

🔬 Variance Drivers:
Material albedo, building geometry (shading), topography, and canopy vs. lawn structure.

💡 Takeaway:
Impervious cover is the dominant microclimate driver. Urban planning—road width, building footprint, and canopy retention—is direct thermodynamic engineering.

📉 Comparing the Solid-to-Tree Ratio with the Land Surface Temperature (LST) data obtained in the previous phase of the study allows for a visual assessment of the relationship between surface sealing and summer surface heating across Calgary’s residential communities.
🔥 The plot reveals a strong pattern for the vast majority of communities: a sharp increase in temperature occurs within the ratio range of 0 to 5. The Downtown Commercial Core stands out as a distinct outlier, where low LST values are driven by deep geometric shading from high-rise buildings. Additionally, neighborhoods such as Manchester, Seton, Redstone, Beltline, and Rangeview, among a few others, slightly diverge from the main trend.

Which Calgary neighborhoods are best built to withstand summer heatwaves? 🌳☀️

To measure structural climate resilience across the city, I conducted a spatial analysis of 193 established residential communities, calculating the Solid-to-Tree Ratio—comparing bare artificial surfaces (asphalt, concrete, rooftops) directly against total tree canopy area.

Here are the Top 10 most shade-rich and climate-resilient communities in Calgary:
🟢 Queens Park Village — 0.3 (Just 0.3 ha of hard surface for every 1 ha of canopy!)
🟢 Discovery Ridge — 0.5
🟢 Roxboro — 0.5
🟢 Wildwood — 0.6
🟢 Rideau Park — 0.7
🟢 Medicine Hill — 0.8
🟢 Upper Mount Royal — 0.8
🟢 Crestmont — 0.9
🟢 Elbow Park — 0.9
🟢 Shaganappi — 0.9

🔥 Top 10 Calgary Communities with the Highest "Shade Deficit"

To measure structural heat risks, I calculated the Solid-to-Tree Ratio—the ratio of bare artificial surfaces (asphalt, concrete, roofs) to total tree canopy area. A higher ratio means more heat-retaining concrete and less natural cooling.

Here are the 10 most shade-deficient residential communities in Calgary:
🔹 Downtown Commercial Core — 56.2 (56.2 ha of hard surfaces for every 1 ha of trees)
🔹 Beltline — 24.6
🔹 Redstone — 23.8
🔹 Seton — 20.8
🔹 Manchester — 17.7
🔹 Rangeview — 16.8
🔹 Symons Valley Ranch — 16.0
🔹 Lower Mount Royal — 13.9
🔹 Country Hills Village — 13.2
🔹 Martindale — 12.4

🔥 It looks like it's time to lock in the current version of the machine learning model (LULC v.6.0). Validation results on an independent test dataset (Confusion Matrix) demonstrate the excellent predictive power of the algorithm:
🔹 Overall Accuracy: 98.29% (95% CI: 98.16% – 98.41%) with a No Information Rate = 60.28% (p-value < 2.2e-16).
🔹 Cohen’s Kappa: 0.9691, confirming high classification reliability even with severe class imbalance.
The model shows a very low error rate for non-vegetated areas (Solid, Balanced Accuracy 99.72%) and water bodies (Water, 99.75%), but expectedly faces challenges at the boundaries between the Lawn (open grass) and Park (sparse trees) classes.
Currently, I am moving on to an advanced analysis of the drivers shaping Urban Heat Islands (UHI) in Calgary and preparing a publication for my website. Stay tuned for updates!

Huh, the new Bears proposal for a stadium is... wildly different than I expected :otter_peek:​ I really like what the renders did with the old Soldier Field columns (and frankly, the UFO they landed inside of it was always a massively ugly waste of money). I feel mostly ambivalent on the proposal I think, provided taxpayers aren't on the hook for it.

If this proposal actually happens, civic leaders from the south side really should lobby hard for the CTA to revisit the Gold Line proposal to take part of the existing Metra electric right-of-way and turn it into a rapid transit corridor. If the city really wants to revitalize the lakefront and drive tourism, they should focus on increasing access between the lakefront parks (the stupid bean/Millennium Park, Grant Park, etc), the Museum Campus (the Field Museum, Shedd Aquarium, Planetarium, Soldier Field), McCormick Place, and Jackson Park (the Museum of Science and Industry and the new Barack Obama Presidential Library). Plus the Gold Line could be used to bring a valuable link for south lake shore communities between the Loop all the way down to South Chicago. :vg_puro_shrug:​ Seems like a win/win to me.

Side note: Also, boost the Green Line back to Jackson Park like it used to be :neofox_what:​ It'd make for a great transfer point for people between the Gold Line and the Green Line.
