What stands behind these Oregon numbers

2 of the 2 metros here report from a named regulatory monitor — Eugene and Springfield, Portland. The dominant pollutant across Oregon today is PM2.5.

We track 2 metropolitan areas in Oregon, not the whole state, and 1 of them has a page of its own. There is no state-wide average here on purpose: averaging 2 metros into one figure would invent a value for all the ground between them. How we measure, and what we refuse to estimate →

Smoke and inversions do not stop at a state line, so when Oregon looks wrong the answer is often next door.
