What the data includes

The current station data listed for this city is focused on particulate matter (PM). In Bangor, Maine the OpenAQ feed provides measurements for two pollutants: PM2.5 and PM10. There are three rows of recent data overall, but only one row each for PM2.5 and PM10, meaning that each pollutant is represented by a single monitoring site – the Bangor MSS station. The most recent timestamp for both pollutants is 2026-02-11 00:00 UTC, which falls within the “updated within 7 days” freshness bucket, so the values are relatively current.

For PM2.5 the recorded values range from a minimum of 6.55 µg/m³ to a maximum of 15.6 µg/m³, with a median of 14.0 µg/m³ and the 10th‑percentile at about 8.04 µg/m³ and the 90th‑percentile near 15.28 µg/m³, indicating modest variability around the upper end of the range. PM10 shows a single reported value of 94.0 µg/m³, which is both the minimum, median and maximum because only one measurement exists. The limited number of stations means coverage is narrow; conditions can differ across neighborhoods or times not captured by these snapshots.
