What the data includes

The OpenAQ feed for Gießen currently contains data from three monitoring sites spread over 17 recorded rows. All eight pollutants tracked in the city’s network are represented: carbon monoxide (CO), nitrogen oxide (NO), particulate matter of 1 µm, 2.5 µm and 10 µm diameter (PM1, PM2.5, PM10), relative humidity, temperature and particle number concentration (UM003). The most recent observations were uploaded on 2026‑02‑10 at 17:00 UTC for CO, NO₂, PM10 and PM2.5, while the oldest timestamp in the set dates back to 2024‑03‑11 at 11:00 UTC for NO. Data for relative humidity, temperature, UM003 and PM1 are older still, last refreshed on 2025‑06‑25 at 18:00 UTC.

Across the recent measurements, PM10 values range from a low of 17.6565 µg/m³ to a high of 45.2932 µg/m³, with a median around 44.27 µg/m³, indicating that most recent samples sit near the upper end of the observed spread. PM2.5 shows a much wider span: the minimum recorded is 1.0438 µg/m³, the maximum 13.7570 µg/m³ and the median only 2.4890 µg/m³, so recent samples are clustered toward the lower end of that range. Temperature readings from the Jacksonstraße (Wiese) site vary narrowly between 28.8173 °C and 29.1485 °C, with a median of 28.9829 °C, while relative humidity stays within a tight band around 34.7 %. The particle number concentration (UM003) spans 270.689 to 338.077 particles/cm³, median 304.383.

Because many rows are dated more than a year old and only three stations contribute data, the picture of air quality in Gießen is limited in both time and space. Conditions can differ noticeably between locations such as Westanlage and Jacksonstraße (Wiese), and the mix of fresh and older timestamps means that recent snapshots may not capture short‑term variations across the whole city.

Data notes

The data shown for Gießen are based on three valid measurements and have been updated within 3 days, with the latest refresh recorded at 2026‑02‑10 17:00 UTC. This snapshot reflects conditions at the time of sampling; air quality can vary across different neighbourhoods and change throughout the day, so values may not represent every location or moment in the city.
