Air quality today

The air quality in Brunssum today is classified as Good. The primary pollutant measured is PM2.5, with a recorded concentration of 0.0998 µg/m³ based on five valid observations from OpenAQ data.

Overall conditions remain within the Good category, and the available measurement confirms the presence of fine particulate matter at the level noted above. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

What the data includes

The Brunssum air‑quality record contains data from a single monitoring site that contributed five separate rows of measurements. All five rows were last refreshed on 2026‑02‑07 12:00 UTC, which falls within the “updated within 7 days” freshness window for every pollutant reported.

The dataset includes five distinct variables. PM1 is recorded at exactly 0.0 µg/m³, with no variation across the rows (minimum, median and maximum are all zero). Fine particulate matter (PM2.5) shows a single value of 0.09983333547910053 µg/m³, again identical for every entry, indicating a very narrow observed range. Relative humidity is captured at 34.83038904401991 % and temperature at 20.801944393581817 °C, each with the same uniform reading throughout the dataset. The particle count metric UM003 registers 84.50244462754992 particles/cm³, also without any spread.

Because every pollutant has only one recorded value, there is no observable distribution or day‑to‑day fluctuation in this snapshot of Brunssum’s air quality. The uniformity suggests that the current data set provides a point‑in‑time picture rather than a detailed temporal profile, and conditions can differ across neighborhoods or at other times of day. Nonetheless, the presence of all five measured parameters—PM1, PM2.5, relative humidity, temperature and UM003—offers a basic multi‑dimensional view of the local environment, albeit limited to a single location and a single recent timestamp.

Data notes

The data shown for Brunssum are based on five valid measurements and were refreshed recently, having been updated within the past seven days (last update: 2026‑02‑07T12:00:00+00:00). This snapshot reflects conditions at the time of collection; air quality can differ across neighbourhoods and change throughout the day, so values may not represent every location or moment in the city.
