Air quality today

The air quality in Chesterfield today is classified as Moderate. The primary pollutant identified is PM2.5 (fine particles).

Measurements recorded by OpenAQ show a PM2.5 concentration of 15.0 µg/m³ and a PM10 level of 18.0 µg/m³, based on seven valid observations. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

What the data includes

The data for Chesterfield includes measurements of nitrogen dioxide (NO₂), ozone (O₃), particulate matter 10 µm or less (PM₁₀) and particulate matter 2.5 µm or less (PM₂.₅). Across the city there are seven recent rows of observations drawn from two monitoring sites, with the newest reading timestamped 2026‑02‑10 20:00 UTC for each pollutant.

All values have been refreshed within the past week, so the dataset reflects very current conditions. NO₂ shows the widest spread, ranging from 16.0 to 29.0 µg/m³ with a median of 22.5 µg/m³; the highest recorded value (29.0 µg/m³) comes from the Chesterfield Roadside sensor. PM₁₀ is considerably tighter, varying only between 16.0 and 18.0 µg/m³ and centring around a median of 17.0 µg/m³ at the same roadside location. PM₂.₅ is even more consistent, recorded between 14.0 and 15.0 µg/m³ with a median of 14.5 µg/m³, again from Chesterfield Roadside. Ozone has a single reported value of 24.0 µg/m³ at the Loundsley Green site, indicating that ozone coverage is limited to one monitoring point compared with two for the other pollutants.

These figures illustrate that while NO₂ exhibits notable variability across the city, the particulate metrics are relatively stable in the recent sample set. The dataset’s breadth is modest—only two stations contribute data—but every entry is up‑to‑date, giving a clear snapshot of current air quality despite the limited spatial coverage.
