Air quality today

The air quality in Grafhorst today falls into the USG category according to the Duck assessment. The main pollutant identified is PM2.5, with a measured concentration of 45.99 µg/m³ based on five valid observations reported through OpenAQ.

Data for this location show that fine particulate matter (PM2.5) is the primary concern at the moment, while no PM10 value is available. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

What the data includes

Grafhoren’s OpenAQ feed contains a single monitoring station that reports six variables: PM1, PM10, PM2.5, relative humidity, temperature and particle count (UM003). The data set therefore consists of one row per pollutant, giving a total of six recorded values for the city.

The most recent measurements were taken on 2026‑02‑10 at 22:00 UTC for five of the variables, showing that the sensor is providing fresh information for PM1 (27.68 µg/m³), PM2.5 (45.99 µg/m³), relative humidity (73.54 %), temperature (10.41 °C) and UM003 (4 712.71 particles/cm³). The PM10 reading is older, last updated on 2025‑01‑13 at 23:00 UTC, so its value of 56.95 µg/m³ reflects conditions from more than a year ago.

All six pollutants have a single reported figure, which also serves as the minimum, median and maximum for each parameter because only one observation is available. This means there is no observed spread or variability in the data; the values represent a snapshot rather than a range of recent conditions. Because the dataset includes just one station, spatial coverage across Grafhoren is limited – variations that might exist elsewhere in the municipality are not captured.

In summary, the city’s air‑quality profile currently offers up‑to‑date readings for five pollutants and an older PM10 value, all derived from a single monitoring location. Users should keep in mind that conditions can differ across neighborhoods and over time, and the present data set does not provide information on temporal trends or variability.

Data notes

The data shown for Grafhorst are based on five valid measurements and were refreshed recently, with the latest update recorded at 2026‑02‑10T22:00:00+00:00 (updated within 3 days). This snapshot reflects conditions at the time of measurement; air quality can differ across neighbourhoods and change throughout the day, so values may not represent every location or moment in the city.
