What the data includes

The dataset for Namur includes four measured pollutants – nitrogen dioxide, ozone, PM10 and PM2.5 – all reported from a single monitoring location (code 43R401 – NAMUR). In total there are eight rows of data, but they all correspond to the same station, so spatial coverage across the city is limited to that one site.

The most recent values are fairly fresh: nitrogen dioxide, PM10 and PM2.5 were last updated on 2026‑02‑10 at 18:00 UTC, while ozone was recorded on 2026‑02‑09 at 11:00 UTC. This means the data for three pollutants is within the past three days and the ozone reading is still within a week of collection. All four pollutants show a single reported value – the minimum, median and maximum are identical – indicating that each measurement currently consists of one observation rather than a range over time.

Specifically, nitrogen dioxide stands at 13.0 µg/m³, ozone at 49.5 µg/m³, PM10 at 1.771 µg/m³ and PM2.5 at 0.3595 µg/m³. Because each pollutant has only one data point from the same location, there is no spread to describe variability; the reported figures represent the sole recent reading for Namur. Consequently, while the timestamps are up‑to‑date, the limited station count means that conditions can differ in other parts of the city and at other times not captured by this snapshot.

Data notes

The dataset for Namur includes eight valid measurements and is updated within three days, with the most recent data recorded on 2026‑02‑10 at 18:00 UTC. These figures represent a snapshot of ambient conditions across the city; air quality can differ by specific location and time of day, so values may not reflect conditions everywhere or at every moment.
