Air quality today
The air quality in Hora Svaté Kateřiny is classified as Good today. The main pollutant identified is PM10, and the reference value for this particle size is 5.0 µg/m³ based on two valid measurements reported through OpenAQ.
No additional pollutants are highlighted, and the data set consists of only the two recorded values that support the current assessment. 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 Hora Svaté Kateřiny currently contains measurements from a single monitoring site, Rudolice v Horach, which provides two pollutant rows – one for ozone (O₃) and one for particulate matter ≤10 µm (PM10). Both pollutants were recorded at the same timestamp, 2026‑02‑10 14:00 UTC, and the data are marked as updated within the last three days, indicating that the freshest observations are only a few days old.
For ozone the reported values are all identical: the minimum, median, 10th percentile, 90th percentile and maximum each equal 46.3 µg/m³. This uniformity shows that, at the time of measurement, O₃ levels did not vary across the sampled period or location. The same pattern holds for PM10, where every statistical indicator – minimum through maximum – is 5.0 µg/m³, reflecting a single consistent reading for fine particulate matter.
Because the dataset consists of just one station and each pollutant has only one recorded value, there is no spread or temporal depth to describe trends or variability. The coverage therefore is limited to a snapshot from Rudolice v Horach on 2026‑02‑10, and conditions elsewhere in Hora Svaté Kateřiny may differ at other times of day or in other neighborhoods. Users should keep in mind that the current picture is based on a very small sample size, with all available data being recent but singular for each pollutant.

Data notes
The data shown for Hora Svaté Kateřiny are based on two valid measurements and were refreshed recently, with the latest update recorded on 2026‑02‑10 at 14:00 UTC (updated within 3 days). This snapshot reflects conditions at the time of sampling; air quality can differ across neighborhoods and change throughout the day, so values may not represent every location or moment in the city.
