Air quality today

The air quality in Vielsalm is currently classified as Good. The primary pollutant identified is PM2.5 (fine particles).

Measurements from six valid observations show a PM2.5 concentration of 0.0 µg/m³ and a PM10 concentration of 0.0 µg/m³, as reported by OpenAQ. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

What the data includes

The Vielsalm air‑quality record consists of a single monitoring station (43N085 – VIELSALM) that supplies data for six common pollutants: carbon monoxide, nitrogen dioxide, ozone, particulate matter ≤ 10 µm, particulate matter ≤ 2.5 µm and sulphur dioxide. All six measurements are present in the dataset, but the amount of information varies across them. The most recent update for every pollutant was recorded on 2026‑02‑10 at 18:00 UTC, so the data are all fresh within the last three days.

Carbon monoxide shows a single reported value of 120.0 µg/m³, which is also its minimum, median and maximum – there is no observed spread in the record. Nitrogen dioxide and ozone behave similarly, each with one constant reading (3.0 µg/m³ for NO₂ and 51.0 µg/m³ for O₃). In contrast, both particulate‑matter series are recorded as zero across the board, giving a uniform range of 0.0 µg/m³. Sulphur dioxide is reported at 1.5 µg/m³ with no variation.

Because only one station contributes data, the dataset cannot capture spatial differences within Vielsalm; conditions may differ in other neighbourhoods or at other times. The lack of variability—each pollutant having identical minimum, median and maximum values—indicates that the current record provides a snapshot rather than a detailed distribution. Users should keep in mind that while the timestamps are recent, the single‑point coverage limits insight into broader temporal trends or local hotspots.

Data notes

The data shown for Vielsalm is based on six valid measurements and was refreshed recently, with the latest update recorded at 2026‑02‑10T18:00:00+00:00 (updated within 3 days). This snapshot reflects conditions captured at that time; however, air quality can differ across neighborhoods and change throughout the day, so values may vary locally and temporally.
