Heat, Air Quality, and Comfort in Downtown Atlanta

Heat and “Urban Heat Island” Effect

In 30303, large paved areas and tall buildings absorb heat, especially in summer. This can cause:

Hot, stagnant days can sometimes be associated with reduced air quality, particularly near major roadways like the Downtown Connector (I-75/85). On these days, many people:
