What the data includes

The current station data listed for this city is focused on particulate matter (PM). In Coulommiers the OpenAQ feed provides measurements for two pollutants – PM10 and PM2.5 – across four recent observations collected from two monitoring sites. The most recent values were recorded on 2026-02-10 at 15:00 UTC, so the dataset is fresh within the last three days for both particle sizes.

PM10 readings range from a low of 5.2 µg/m³ to a high of 28.3 µg/m³, with a median of about 16.8 µg/m³ and the middle 80 % of values falling between roughly 7.5 and 26.0 µg/m³. PM2.5 shows a narrower spread, from 3.0 to 11.8 µg/m³, median 7.4 µg/m³, and an 80 % interval of approximately 3.9 to 10.9 µg/m³. Because only two stations contribute data, the coverage is limited; conditions can differ across neighborhoods or at times not captured by these recent snapshots.
