What the data includes

The OpenAQ feed for Dübendorf currently contains data from three monitoring rows covering ten measured pollutants: carbon monoxide (CO), nitrogen dioxide (NO2), ozone (O3) – although O3 has no recent values in this snapshot – particulate matter of three size fractions (PM1, PM2.5, PM10), relative humidity, sulfur dioxide (SO2) – also without a current reading – temperature, and ultrafine particle count (UM003). The dataset comprises 24 total rows, but only four rows have been updated within the last seven days; the most recent timestamps are from 2026‑02‑10 at 20:00 UTC for CO and NO2, and at 22:00 UTC for PM1, PM2.5, PM10, relative humidity, temperature and UM003.

Across the fresh measurements, particulate matter shows a modest spread: PM10 values range from about 20.4 to 39.5 µg/m³ with a median of 32.7 µg/m³, while PM2.5 varies between 20.1 and 38.98 µg/m³ (median 34.8 µg/m³). The smallest particles (PM1) are less variable, ranging from 20.35 to 25.16 µg/m³ with a median near 21.22 µg/m³. Relative humidity stays tightly clustered between 68 % and 69 %, and temperature is almost constant around 8.28 °C (minimum 8.17 °C, maximum 8.28 °C). The ultrafine particle count (UM003) spans from roughly 2 978 to 3 952 particles per cm³, median 3 281.

Because only a handful of rows are recent, the picture is limited to a snapshot taken on 2026‑02‑10. Many older or unknown entries mean that conditions can differ across neighborhoods and times not captured here. Users should keep in mind that the available data reflects a narrow time window and does not represent continuous monitoring for all listed pollutants.

Data notes

The dataset for Dübendorf includes 19 valid measurements and is Updated within 3 days, with the latest values recorded on 2026‑02‑10T22:00:00+00:00. These figures represent a snapshot of conditions at specific monitoring points; air quality can differ across neighborhoods and change throughout the day, so the values shown may not reflect conditions everywhere in the city at any given moment.
