Air quality today

The air quality in Kiel today is classified as Moderate. The primary pollutant identified is PM2.5 (fine particles). Measurements show a PM2.5 reference value of 27.152 and a PM10 reference value of 33.085, based on eight valid observations.

Data are shown via OpenAQ. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

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 Kiel includes measurements of nitrogen dioxide (NO2), ozone (O3), particulate matter ≤ 10 µm (PM10) and particulate matter ≤ 2.5 µm (PM2.5). In total ten recent rows are available, coming from four monitoring stations that report at least one of the pollutants. All reported values were last updated on 2026‑02‑10 at 18:00 UTC, so the information reflects conditions from a single recent snapshot rather than a continuous time series.

Across the city the observed NO2 concentrations range from 5.25 µg/m³ up to a maximum of 48.854 µg/m³, with a median value of about 34.65 µg/m³ and the 10th‑percentile at 11.54 µg/m³. Ozone shows a broader spread, from 14.337 µg/m³ to 71.85 µg/m³, median 43.09 µg/m³, and the lower decile near 20.09 µg/m³. PM10 values are comparatively tight, varying between 25.384 µg/m³ and 33.085 µg/m³; the median sits at 29.23 µg/m³ and the 90th‑percentile reaches 32.31 µg/m³. PM2.5 follows a similar narrow band, from 21.523 µg/m³ to 27.152 µg/m³, with a median of 24.34 µg/m³ and the upper decile at 26.59 µg/m³.

The coverage is uneven: NO2 is reported by four stations, while O3, PM10 and PM2.5 each have data from only two stations. Consequently, spatial detail is richer for nitrogen dioxide than for the other pollutants. Because all measurements stem from a single recent timestamp, they capture the state of air quality at that moment but do not reflect daily or longer‑term variations; conditions can differ across neighborhoods and over time.

Data notes

The data shown for Kiel are based on eight valid measurements and were updated within 3 days, with the latest refresh recorded at 2026‑02‑10T18:00:00+00:00. This snapshot reflects conditions at a specific time and place; air quality can differ across neighborhoods and change throughout the day, so values may not represent the entire city at any given moment.
