Air quality today

The air quality in Visé, Liège, Belgium is currently classified as Moderate. The primary pollutant measured is PM2.5, which represents fine particulate matter with a diameter of 2.5 micrometers or less. The latest reported concentration is 33.31 µg/m³, based on five valid observations. No PM10 value is available for this reporting period. These figures are drawn from the most recent data supplied by OpenAQ.

All values are sourced from the OpenAQ network, which aggregates measurements from participating monitoring stations in the area. The dataset includes five distinct measurement points collected during the reporting interval. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

What the data includes

The dataset for Visé, Liège, Belgium currently contains five recent records from a single monitoring site, identified as Richelle. All five rows were last updated on 2026-01-28 18:00 UTC, and each falls within the “less than 30 days” freshness bucket, meaning the information is up‑to‑date. The pollutants measured at this location are PM1, PM2.5, relative humidity, temperature and UM003, giving a total of five distinct air‑quality variables.

For each pollutant the most recent value is the only value recorded, so the minimum, median and maximum are identical. PM1 registers at 15.225333340962727 µg/m³, PM2.5 at 33.31133327484131 µg/m³, relative humidity at 66.93033383687337 %, temperature at 9.567499939600626 °C and UM003 at 794.2943339029948 particles/cm³, all measured at Richelle on 2026-01-28 18:00 UTC. Because the statistical spread (p10‑p90) collapses to a single point for every parameter, the dataset does not show any variability over time or across different locations within the city.

The coverage is therefore limited to one station, which means the snapshot reflects conditions at that specific point rather than the whole urban area. While the data are fresh, the lack of multiple sites or repeated measurements implies that air‑quality conditions can differ elsewhere in Visé and at other times of day. Users should keep in mind that this single‑site snapshot provides a precise but geographically narrow view of the current environment.
