🔥 Median Land Surface Temperature in Calgary: Summer 2026 🛰️ Midday records show consistent thermal clustering across Calgary: 🔹 Cool zones (≤20–25 °C): Bow River, Glenmore Reservoir, deep ravines (stable thermal baseline). 🔹 Thermal buffering (30–35 °C): Mature tree canopy zones; direct shading & evapotranspiration mitigate heating. 🔹 Hot zones & heat cores (≥45–50 °C): Industrial sectors, warehouses, open rooftops/parking of malls (CF Chinook Centre, CF Market Mall) and transit yards (Calgary Transit's Spring Gardens & Anderson garages). ❗ QA/QC & Method Reliability: To isolate persistent patterns rather than daily anomalies, the seasonal median was calculated using Landsat 8/9 (30 m): 🔹 Observation Density mapped clear-sky overpasses (0–9). 🔹 Only pixels with ≥4 valid observations were included (≤3 excluded to remove noise and cloud artifacts). #RemoteSensing #SpatialDataScience #UrbanHeatIsland #EarthObservation #GIS #Calgary #GreennessOfCalgary #RStats #YYC #Landsat
