2 of the 2 metros here report from a named regulatory monitor — Northeast Urban, Northeast Urban. The dominant pollutant across New Jersey today is O3.

We track 2 metropolitan areas in New Jersey, not the whole state, and none of them has its own page yet — a metro page ships only after thirty days of our own history, and that clock is running. 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 →
