Theory 09/Existing data/Urban climate
Heat Islands Follow Sky View
The claim
Urban heat island intensity is set by sky-view factor more than by green cover, because radiative loss dominates sensible cooling at night.
01Mechanism
Narrow streets trap longwave radiation; the geometry sets nocturnal cooling.
02Prediction
Intensity should track sky-view factor better than canopy fraction.
03Refutation
Intensity tracking green cover would remove geometry.
