Why the air in metro Phoenix is fresher these days


Vehicles driving on the roads are the biggest contributor to the man-made ozone in the Phoenix area. But because the traffic is less, we’re seeing less air pollution. 

Phoenix was below average for moderate ozone days for the month of March. Plus, with Phoenix’s recent wet weather, it helped wash pollutants out of the air.

And better air quality isn’t just being seen in Phoenix but across the globe.
