Alaska air quality today

Updated · LIVE · 2 metros tracked

Across the 2 Alaska metros we measure, air is worst right now in Fairbanks at AQI 54 (Moderate) and cleanest in Anchorage at AQI 6. That is a 48-point spread inside one state — a state-level number would hide it, which is why this page does not publish one.

What stands behind these Alaska numbers

2 of the 2 metros here report from a named regulatory monitor — Anchorage, Fairbanks. The dominant pollutant across Alaska today is PM10 in some metros, PM2.5 in others.

We track 2 metropolitan areas in Alaska, 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 →
