Pog?

Remember those photos of my morning commute? Remember the mountains in them? Well, in these shots you can barely see them. We don't have smog here, really, and never have smog alerts.

They have pre-empted a lot of that trouble with really high emissions standards. All cars have to be tested before licensing.

What you're seeing here is a typically crystal-clear day in Tucson - high up. Nearer the ground, you see a thick haze of pollen and dust that the winds have kicked up and spread skyward. If "smog" is a combination of "smoke" and "fog", what would you call a combination of pollen and dust - "pust"? Or fog-like pollen clouds - "pog"?
