Air quality today
The air quality in Constance today falls into the Moderate category. The primary pollutant identified is PM2.5 (fine particles). Measurements show a PM2.5 reference value of 24.0 and a PM10 reference value of 26.1, based on four valid observations reported through OpenAQ.
These figures reflect the current assessment for the city without additional interpretation. 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 dataset for Konstanz contains a single monitoring station that reports five pollutants: nitrogen monoxide (NO), nitrogen dioxide (NO₂), ozone (O₃), particulate matter ≤ 10 µm (PM₁₀) and particulate matter ≤ 2.5 µm (PM₂.₅). In total there are five rows of data, one for each pollutant, all measured in micrograms per cubic metre.
The most recent values were recorded on 2026-02-10 20:00 UTC for NO₂, O₃, PM₁₀ and PM₂.5, showing that the majority of the dataset is up‑to‑date within the last three days. The NO measurement is older, dated 2024-03-11 11:00 UTC, so it does not reflect current conditions for that specific gas. Because each pollutant has only a single recorded value, the minimum, median and maximum are identical – for example, NO₂ is consistently reported as 33.29 µg/m³, O₃ as 1.799 µg/m³, PM₁₀ as 26.1 µg/m³ and PM₂.5 as 24.0 µg/m³.
With just one station providing a single data point per pollutant, the coverage is limited to that location and does not capture spatial variation across Konstanz. The timestamps indicate that four of the five pollutants are refreshed very recently, while NO remains outdated by almost two years. Consequently, any assessment based on this set should note the narrow geographic scope and the mixed freshness of the measurements; conditions elsewhere in the city or for NO may differ from what is shown here.

Data notes
The data shown for Constance are based on four valid measurements and were refreshed recently, with the latest update recorded at 2026‑02‑10T20:00:00+00:00 (updated within 3 days). 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.
