Bad Air

Air over west Phoenix

Dust and haze over west Phoenix

We have a pollution advisory till Thursday night.  Phoenix is in something of a valley, and during the summer heat we’re prone to inversion layers.  On top of that the west valley area is still largely agricultural, so when the farmers disk their fields the amount of dust in the air is truly impressive.  We live far enough west that we generally have clean air (dairy farms aside!) but you can see the dust and pollution clearly to the east.
