Air quality today
The air quality in Mladá Boleslav today is classified as Moderate. The primary pollutant identified is PM2.5, with a measured concentration of 17.4 µg/m³. In addition, the level of PM10 recorded is 10.2 µg/m³, based on four valid measurements.
Data are shown via OpenAQ and reflect the current monitoring results for the city. 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 air‑quality dataset for Mladá Boleslav contains a single monitoring station that reports five pollutants: nitrogen monoxide (NO), nitrogen dioxide (NO₂), ozone (O₃), particulate matter ≤10 µm (PM₁₀) and particulate matter ≤2.5 µm (PM₂.₅). All measurements are expressed in micrograms per cubic metre.
The most recent data point for NO dates back to 2024‑03‑11 10:00 UTC, while the other four pollutants have updates from 2026‑02‑10 14:00 UTC, meaning that the bulk of the current record is less than three days old. Each pollutant shows a single recorded value with no variation across the dataset: NO 2.7 µg/m³, NO₂ 11.3 µg/m³, O₃ 42.5 µg/m³, PM₁₀ 10.2 µg/m³ and PM₂.₅ 17.4 µg/m³. Consequently the minimum, median, 10th percentile, 90th percentile and maximum are identical for every substance.
Because only one station contributes data, there is no spatial spread within the city; conditions measured at this point may not represent other neighborhoods or micro‑environments. The dataset also lacks any older or unknown‑age entries – all rows are classified as recent, with the exception of the NO reading which is over a year old relative to the others. This uneven timestamp distribution highlights that while most pollutants are captured in near‑real time, the nitrogen monoxide record is outdated and should be interpreted with caution.
Overall, the dataset provides a concise snapshot of five key air‑quality parameters for Mladá Boleslav, but its single‑station coverage and the solitary historic NO value limit the ability to assess broader temporal or geographic patterns within the city.
