Ugh, I don't even want to bring this up...
In Phoenix, our pollution was so bad we called the nasty air, in the most loving way, the 'brown cloud'.
One of the refreshing things about Portland is that we don't really have one. However, in the late summer the air would always get 'hazy' but never brown. The rest of the year the skies were crisp blue.
In the last two years I've noticed, even on windy winter days that the haze never goes away now. I've been meaning to ask if anyone else sees this, and than PDX City-State posted another picture thread and it looks really hazy, yet it is only May.
Are we getting a brown cloud? If so, from what? Pollution from China? Too much congestion? The Threemile Canyon farm and PGE's coal plant just east of the Gorge?
