What stands behind these Texas numbers

5 of the 5 metros here report from a named regulatory monitor. The dominant pollutant across Texas today is PM2.5.

We track 5 metropolitan areas in Texas, not the whole state, and 1 of them has a page of its own. There is no state-wide average here on purpose: averaging 5 metros into one figure would invent a value for all the ground between them. How we measure, and what we refuse to estimate →
