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 Horní Stropnice air‑quality record includes measurements for ozone (O₃) and particulate matter ≤10 µm (PM10). Both pollutants are represented by a single monitoring location, Hojna Voda, so the dataset contains two rows in total – one for each substance. The most recent values were logged on 2026‑02‑10 at 14:00 UTC, which places every entry within the last three days and therefore qualifies as fresh data.
For ozone, the only reported figure is 30.7 µg/m³, which also serves as the minimum, median and maximum across the dataset because there is just one observation. The same pattern holds for PM10, with a solitary reading of 3.5 µg/m³ that defines its entire statistical spread. Because each pollutant has only one data point, typical descriptive statistics such as inter‑quartile range or variability cannot be derived; the reported values are both the central tendency and the full extent of observed concentrations.
The coverage is limited to a single site, meaning spatial variation within Horní Stropnice is not captured by this set. While the timestamps are recent, the lack of multiple stations or repeated measurements over time restricts any assessment of how conditions might differ across neighborhoods or change throughout the day. Consequently, the available data give a snapshot of ozone and PM10 at one location on a specific date, but they do not reflect broader temporal trends or geographic diversity within the city.

Data notes
The data shown for Horní Stropnice is based on two valid measurements and was updated within 3 days, with the latest reading recorded at 2026‑02‑10 14:00 UTC. This snapshot reflects conditions at a specific time and place; air quality can vary across different neighborhoods and moments throughout the day, so values may not represent the entire city’s current situation.
