This friendly indicator summarizes the latest city readings. For health guidance, please see: EPA AirNow or WHO.
Air quality today
The air quality in Wierden today falls into the Moderate category. The primary pollutant measured is PM2.5 (fine particles), with a reported concentration of 13.68 µg/m³ based on five valid observations from OpenAQ data.
No other pollutants reached measurable levels, and the dataset does not include a PM10 value for this period. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.
Latest sensor values
PM categories follow US EPA AQI breakpoints, shown here as an estimate derived from the latest valid measurements (this project does not compute EPA NowCast/24-hour AQI yet).
What the data includes
The dataset for Wierden contains six measurement rows drawn from a single monitoring site. All of the pollutants tracked by OpenAQ are represented: fine particles (PM1 at 14.46 µg/m³), coarse particles (PM10 at 56.95 µg/m³), fine‑to‑coarse mix (PM2.5 at 13.68 µg/m³), relative humidity (86.82 %), temperature (6.49 °C) and particle count in the 0.3 µm range (UM003 at 2,149.5 particles/cm³). For five of these parameters the most recent reading was taken on 2026‑02‑10 at 22:00 UTC, indicating very fresh data for those variables. The PM10 measurement is older, last updated on 2025‑01‑13 at 23:00 UTC, so its timestamp lags by more than a year compared with the others.
Because each pollutant has only one recorded value, the statistical spread is essentially zero – the minimum, median and maximum are identical for every metric. This means the dataset does not capture variability over time or across different locations within the city; it provides a single snapshot rather than a range of conditions. The uniform freshness of most parameters suggests recent coverage, yet the outdated PM10 reading highlights an uneven update pattern across pollutants.
Overall, the data set offers a concise picture of current air‑quality related measurements at one point in Wierden, but its limited spatial scope (one station) and lack of multiple observations mean that conditions can differ elsewhere or change throughout the day. Users should keep in mind that this snapshot reflects only the specific time and place recorded.

Data notes
The data shown for Wierden reflects five valid measurements and is updated within three days, with the most recent reading recorded on 2026‑02‑10 at 22:00 UTC. This snapshot provides a current view of air quality across the city, but conditions can differ by neighbourhood and change throughout the day, so local variations may not be captured in these figures.
