Air quality today
The air quality in Landen today is classified as Good. The primary pollutant identified is PM2.5 (fine particles). Measurements show a PM2.5 reference value of 1.727 and a PM10 reference value of 3.3, based on three valid observations.
Data are shown via OpenAQ. 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 air‑quality record for Landen currently draws on a single monitoring station, identified as 42N054 – WALSHOUTEM, which supplies data for all four pollutants tracked in the city: nitrogen dioxide (NO2), ozone (O3), particulate matter 10 µm or smaller (PM10) and particulate matter 2.5 µm or smaller (PM2.5). Because there is only one row of observations, the dataset does not capture spatial variation across different neighbourhoods.
The most recent measurements are very fresh for three of the pollutants, with NO2, PM10 and PM2.5 all last updated on 2026‑02‑10 at 18:00 UTC, meaning the values reflect conditions from just a few days ago. Ozone is an outlier; its latest entry dates back to 2024‑01‑16 at 10:00 UTC, so the ozone figure is considerably older than the others.
All four pollutants show identical single‑value statistics because each has only one recorded reading. NO2 registers exactly 6.0 µg/m³, O3 records 34.5 µg/m³, PM10 stands at 3.3 µg/m³ and PM2.5 is measured at 1.727 µg/m³. Consequently the minimum, median, maximum, 10th percentile and 90th percentile are all the same for each pollutant, indicating no observed spread in the data.
Overall, the dataset provides a very limited snapshot: one location, one value per pollutant, and an ozone reading that is over two years old. While the recent timestamps for three pollutants suggest up‑to‑date information, the lack of multiple stations means city‑wide conditions may differ from what these single measurements show.

Data notes
The data shown for Landen reflects three valid measurements and was refreshed recently, with the latest update recorded on 2026‑02‑10 at 18:00 UTC; it is therefore considered “Updated within 3 days.” This snapshot provides a brief view of current conditions, but air quality can differ across neighbourhoods and change throughout the day, so local variations may not be captured in these figures.
