Air quality today

The air quality in Darmstadt today is classified as Good. The main pollutant identified is PM2.5 (fine particles). Measurements show a PM2.5 value of 5.824 and a PM10 value of 7.63665, based on seven valid observations collected via OpenAQ.

Overall conditions meet the criteria for a Good rating according to the current assessment. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

What the data includes

The dataset for Darmstadt contains measurements for carbon monoxide (CO), nitrogen oxide (NO), nitrogen dioxide (NO₂), ozone (O₃), particulate matter 10 µm or less (PM₁₀), particulate matter 2.5 µm or less (PM₂.₅) and sulfur dioxide (SO₂). The information comes from 12 rows of observations collected at two monitoring stations, so the spatial coverage is limited to a small number of sites within the city.

The most recent values are generally very fresh: for NO₂, PM₁₀, PM₂.₅, O₃ and SO₂ the latest timestamps are all on 2026‑02‑10 18:00 UTC, indicating data that was updated within the last three days. By contrast, CO and SO₂ have older records – the newest CO reading dates back to 2023‑02‑02 00:00 UTC and the most recent SO₂ measurement is from 2023‑03‑26 21:00 UTC, so those pollutants are represented by dated information.

Across the available pollutants the observed ranges are narrow. CO varies between about 185 µg/m³ and 200 µg/m³ with a median near 193 µg/m³; NO spans roughly 1.7 µg/m³ to 8.3 µg/m³, median around 5 µg/m³; NO₂ is recorded between 19.9 µg/m³ and 27.7 µg/m³ with a median of 23.8 µg/m³. Particulate matter shows very little spread – PM₁₀ stays between 7.57 µg/m³ and 7.64 µg/m³ (median 7.60 µg/m³) and PM₂.₅ ranges from 5.82 µg/m³ to 6.05 µg/m³ (median 5.94 µg/m³). Ozone is represented by a single value of 39.17 µg/m³, while SO₂ is recorded at 0.80 µg/m³.

Because the dataset relies on only two stations and several pollutants have older timestamps, the picture it provides reflects conditions at specific locations and times rather than a comprehensive city‑wide view. Users should keep in mind that air quality can differ across neighborhoods and over shorter periods than those captured here.

Data notes

The data shown for Darmstadt reflects seven valid measurements and is marked as Updated within 3 days, with the latest values recorded on 2026‑02‑10 at 18:00 UTC. While these figures provide a current snapshot of citywide air quality, conditions can differ across neighborhoods and change throughout the day, so local variations may not be captured in this summary.
