Air quality today

The air quality in Beroun today is classified as Moderate. The main pollutant identified is PM2.5, fine particulate matter measured at a reference value of 24.4 µg/m³, while the accompanying PM10 level shows a reference value of 25.5 µg/m³ based on three valid measurements.

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

What the data includes

The air‑quality record for Beroun contains a single monitoring station that reports five pollutants: carbon monoxide (CO), nitrogen oxide (NO), nitrogen dioxide (NO₂), particulate matter 10 µm or less (PM₁₀) and particulate matter 2.5 µm or less (PM₂.₅). All measurements are expressed in micrograms per cubic metre.

The most recent data were uploaded on 2026‑02‑10 at 14:00 UTC for CO, NO₂, PM₁₀ and PM₂.5, while the NO reading is older, last updated on 2024‑03‑11 at 10:00 UTC. Because there is only one row of data, the range for each pollutant collapses to a single value: CO registers 457.0 µg/m³, NO 6.4 µg/m³, NO₂ 12.4 µg/m³, PM₁₀ 25.5 µg/m³ and PM₂.₅ 24.4 µg/m³. The median, minimum and maximum are identical for every pollutant, indicating no observed variability within the limited dataset.

With just one station contributing, coverage across the city is minimal and the timestamps show a mixed freshness: four of the five pollutants have measurements from less than three days ago, but the NO value remains over a year old. Consequently, while the current snapshot provides concrete concentrations for each listed pollutant, it does not capture spatial or temporal variations that may exist elsewhere in Beroun.
