Weather patterns! Global warming GOOD!
Probably cars mostly. Emission controls, unleaded fuels and catalytic converters were pretty new then and the 55 MPH speed limit had just been introduced. Not much had been done about smoke stack pollution. As a result we were probably still at our worst air quality.
