Air quality today

The air quality in Halen today is classified as Good. The main pollutant identified is PM2.5, with a measured concentration of 2.80 µg/m³ based on five valid observations reported through OpenAQ.

Data show that fine particulate matter (PM2.5) is the only specific metric available for this assessment. No other pollutants have been reported for the current measurement set. 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 Halen air‑quality dataset contains six recorded parameters from a single monitoring location on Linkhoutsestraat. The pollutants available are PM1, PM10, PM2.5, relative humidity, temperature and the particle count UM003. Because only one station contributes data, the coverage is limited to that specific street rather than representing the whole city.

All values in the set are identical for each pollutant, indicating a single observation per parameter. The most recent measurements were taken on 2026‑02‑10 at 19:00 UTC for PM1 (0.6416666646798451 µg/m³), PM2.5 (2.802833340068658 µg/m³), relative humidity (66.47716636657715 %), temperature (12.241999975840251 °C) and UM003 (289.2916666666667 particles/cm³). The only older entry is the PM10 reading, which dates back to 2025‑01‑13 at 23:00 UTC with a value of 97.90245882670085 µg/m³. Consequently, five of the six parameters are updated within the last three days, while one remains over a year old.

Because each pollutant shows a single recorded figure, there is no spread to describe; the minimum, median and maximum are all the same for every metric. This uniformity highlights that the dataset captures a snapshot rather than a range of conditions, so variations across different parts of Halen or over time cannot be inferred from these numbers alone. Users should keep in mind that air‑quality conditions may differ elsewhere in the city and at other times, given the limited spatial and temporal coverage of the current data.

Data notes

The data shown for Halen reflects five valid measurements and is updated within three days, with the most recent reading recorded on 2026‑02‑10 at 19:00 UTC. These values provide a current snapshot of ambient air quality across the city, but conditions can differ by neighbourhood and time of day, so local variations may not be captured in this summary.
