This is pretty cool. Real-time air quality measurements for 17 locations around Puget Sound. At the moment, every monitoring station is showing good air quality. It’ll be interesting to check back periodically as wintertime inversions trap pollution in the basin.

Anyone know of other web-based measurements like this one for other places in the Northwest?

UPDATE:Here’s a clickable map of county-by-county air quality for Washington state. (Hat tip to the ever-vigilant Alan Durning.)
