🔥 Biophysical Cooling Threshold in Calgary: Confirmation of Invariance (Summer 2025 vs Summer 2026) 🛰️ Despite the interannual shift in the temperature baseline and weather differences between the two seasons, the critical threshold for the onset of evapotranspirative cooling based on NDVI demonstrated high stability. Around values of approximately 0.35, a trend inflection and the onset of effective radiative cooling across the urban area are observed. ☝️ What this means from the perspective of applied geoecology: 🔹 Cooling onset: Actual suppression of surface overheating is activated only after crossing the 0.35 threshold, when vegetation density and tree canopy cover provide comprehensive direct shading and transpirational heat dissipation.
