I thought the smog is just dust from the desert. Isn't this why LA skies are so clear after a rainy day?

- sneak 4y agoSmog is sulphur dioxide and other anthropogenic air pollution, mostly from vehicle exhaust and other sources of combustion.
- tppiotrowski 4y agoI wasn't challenging what smog is. I was pointing out that LA air quality no longer suffers from smog like it did in the 1970s. Any hazy skies around LA are now more a product of dust in the air and not vehicle emissions.
