Air quality today
The air quality in Kadaň is currently classified as Moderate. The primary pollutant measured is PM2.5 (fine particles). Recent data show a PM2.5 concentration of 10.7 µg/m³ and a PM10 level of 25.3 µg/m³, based on five valid measurements collected through OpenAQ.
These values reflect the present monitoring snapshot for Kadaň. 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 Kadaň currently contains measurements from a single monitoring location in the suburb of Tusimice, giving six rows of data – one for each pollutant that is tracked: nitrogen monoxide (NO), nitrogen dioxide (NO₂), ozone (O₃), particulate matter ≤ 10 µm (PM₁₀), particulate matter ≤ 2.5 µm (PM₂.₅) and sulfur dioxide (SO₂). All values are reported in micrograms per cubic metre (µg/m³).
Freshness varies across the series. The most recent updates for NO₂, O₃, PM₁₀, PM₂.₅ and SO₂ were recorded on 2026‑02‑10 at 14:00 UTC, indicating that these five pollutants have data that are less than three days old. In contrast, the NO measurement is older, last updated on 2024‑03‑11 at 10:00 UTC, and is flagged as “Old data”. Because there is only one sensor feeding all six rows, the dataset does not capture spatial variation within the city; conditions can differ in other neighbourhoods or at different times of day.
The numbers themselves are tightly clustered. For each pollutant the minimum, median and maximum values are identical, showing no observed spread during the reporting period: NO is 0.6 µg/m³, NO₂ is 7.1 µg/m³, O₃ is 51.9 µg/m³, PM₁₀ is 25.3 µg/m³, PM₂.5 is 10.7 µg/m³ and SO₂ is 2.9 µg/m³. This uniformity reflects the single‑point nature of the data rather than a lack of variability in the atmosphere. Consequently, while the dataset provides a current snapshot for each listed pollutant at Tusimice, it offers limited insight into broader city‑wide air quality patterns.
