Editing Urban heat island intensity (section)

== Aggregation Semantics ==
Geographic aggregation of urban heat island intensity involves synthesizing temperature differentials across defined urban and peri-urban zones to produce representative indices for cities or metropolitan areas. Temporal aggregation may include averaging over diurnal, seasonal, or annual periods to capture typical or extreme heat amplification patterns. Cross-signal aggregation can integrate urban heat island intensity with related environmental signals such as heat index or population-weighted heat exposure to assess combined heat stress impacts. Aggregation practices aim to balance spatial resolution with temporal consistency to support comparative analyses across regions and timeframes.
