Air quality today
The air quality in Groot‑Ammers is currently classified as Moderate. The main pollutant identified is PM2.5, with a measured concentration of 23.19 µg/m³ based on five valid observations reported through OpenAQ.
Data for this assessment come from a limited set of measurements and reflect the conditions at the time they were recorded. 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 dataset for Groot‑Ammers contains a single monitoring location – Graafland – which supplies one row of data for each of the five measured variables: PM1, PM2.5, relative humidity, temperature and UM003 (particle count). All five pollutants are therefore represented, but there is no broader network of stations in the city.
The most recent readings were all recorded at the same moment, 2026‑02‑10 22:00 UTC, so the data are uniformly fresh across every parameter. For PM1 the value is 8.10816666285197 µg/m³, while PM2.5 registers 23.194500001271567 µg/m³. Relative humidity stands at 65.97733357747396 %, temperature at 12.312333329518637 °C and the particle concentration measured by UM003 is 668.2556660970052 particles/cm³. Because each pollutant has only one observation, the minimum, median and maximum are identical, giving a zero spread for every metric.
With just one sensor row, the coverage is limited to conditions at Graafland and does not capture spatial variation across Groot‑Ammers. The dataset’s freshness is high – all values were updated within the last seven days – but the lack of multiple stations means that temporal trends or differences between neighbourhoods cannot be assessed from this source alone.

Data notes
The data shown for Groot‑Ammers is based on five valid measurements and was refreshed within the past three days, with the latest update recorded at 2026‑02‑10T22:00:00+00:00. This snapshot reflects conditions at the time of sampling; air quality can differ across neighbourhoods and change throughout the day, so values may not represent every location or moment in the city.
