Air quality today

The air quality in Tatabánya today is classified as Moderate. The primary pollutant measured is PM2.5. Current readings show a PM2.5 concentration of 24.0 µg/m³ and a PM10 concentration of 26.0 µg/m³ based on five valid measurements.

These values are provided through the OpenAQ platform, which aggregates data from participating monitoring stations. The dataset includes five recent observations that meet quality criteria. The information reflects the conditions at the time of measurement and does not include forecasts or trend analysis. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

What the data includes

The Tatabánya air‑quality feed pulls data from two monitoring stations and currently contains eleven measurement rows. All six key pollutants are represented: carbon monoxide (CO), nitrogen dioxide (NO₂), ozone (O₃), particulate matter ≤ 10 µm (PM10), particulate matter ≤ 2.5 µm (PM2.5) and sulphur dioxide (SO₂). For CO, O₃, PM10, SO₂ and PM2.5 the most recent reading was recorded on 2026‑02‑10 at 20:00 UTC, while the latest NO₂ value dates from 2026‑01‑30 at 22:00 UTC. Six rows have been updated within the past 30 days, but none are newer than three days, and five rows have an unknown freshness status.

Across the pollutants the observed concentrations span a wide range. CO values range from about 414 µg/m³ up to a peak of 605 µg/m³, with a median near 509 µg/m³ and the central 80 % of observations falling between roughly 433 µg/m³ and 586 µg/m³. NO₂ shows a lower overall level, varying from 2.3 µg/m³ to 20.5 µg/m³, median 11.4 µg/m³, with most readings clustered between 4.1 µg/m³ and 18.7 µg/m³. O₃ is comparatively stable, staying between 25.7 µg/m³ and 28.6 µg/m³, median 27.1 µg/m³. PM10 ranges from 5.1 µg/m³ to 26 µg/m³, median 15.5 µg/m³, while SO₂ is tightly grouped between 2.5 µg/m³ and 2.76 µg/m³, median 2.63 µg/m³. PM2.5 has a single recorded value of 24 µg/m³, indicating limited coverage for this fraction.

The dataset therefore offers recent, multi‑pollutant information from a modest number of stations, but the depth of coverage differs: CO, NO₂, O₃, PM10 and SO₂ each have two rows, whereas PM2.5 is represented by only one. Because measurements are not uniformly recent and spatial coverage is limited to two sites, the recorded values capture only a snapshot of conditions; actual air quality in Tatabánya can vary by location and moment.
