Air quality today
The air quality in Rožďalovice today is classified as Moderate. The primary pollutant identified is PM2.5, fine particulate matter, with a measured concentration of 25.3 µg/m³. In addition, the level of PM10 recorded is 20.6 µg/m³, based on four valid observations from OpenAQ data.
Overall conditions reflect the Moderate category and the reported values for both PM2.5 and PM10. 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 Rožďalovice air‑quality dataset contains five measured pollutants – nitrogen monoxide (NO), nitrogen dioxide (NO₂), particulate matter 10 µm or less (PM₁₀), particulate matter 2.5 µm or less (PM₂.₅) and sulphur dioxide (SO₂). All of these values come from a single monitoring station, Rozdalovice‑Ruska, so the dataset represents one location rather than a citywide network.
The most recent data points were recorded on 2026‑02‑10 at 14:00 UTC for NO₂, PM₁₀, PM₂.₅ and SO₂, each flagged as “Updated within 3 days”. The NO measurement is older, dated 2024‑03‑11 at 09:00 UTC and labelled “Old data”. Because there is only one row per pollutant, the reported minimum, median and maximum are identical for each substance. For example, NO₂ registers a single value of 9.8 µg/m³, PM₁₀ shows 20.6 µg/m³, PM₂.₅ records 25.3 µg/m³, while both NO and SO₂ are measured at 3.7 µg/m³.
With just one station contributing five rows, the coverage is limited to a single point in Rožďalovice, and the dataset reflects a snapshot rather than continuous monitoring across the town. The freshness of most pollutants is good – all but NO have timestamps from less than three days ago – yet the older NO reading highlights an uneven update frequency. Because the data set consists of single values per pollutant, there is no observed spread or variability; any change in conditions elsewhere in the city would not be captured by this source.
