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 dataset for Prachatice contains measurements for four pollutants – nitrogen monoxide (NO), nitrogen dioxide (NO₂), ozone (O₃) and particulate matter PM10 – collected from a single monitoring station that contributes four separate rows, one for each pollutant. The most recent data points are fairly current for three of the gases: NO₂, O₃ and PM10 were all recorded on 2026‑02‑10 at 14:00 UTC, while the NO reading is older, dated 2024‑03‑11 at 10:00 UTC. This means that, apart from NO, the latest observations are less than three days old, whereas the nitrogen monoxide value reflects a measurement taken almost two years ago.
All four pollutants show a single reported value with no variation across the dataset. For NO the concentration is exactly 1.0 µg/m³; for NO₂ it is 8.6 µg/m³; O₃ registers at 44.5 µg/m³; and PM10 measures 8.1 µg/m³. Because each pollutant has only one recorded figure, the minimum, median, maximum, as well as the 10th and 90th percentiles are identical to that value, indicating no observed spread in the data for any of them.
The coverage is therefore limited: only one monitoring location supplies all four pollutants, and the dataset consists of a single row per pollutant. While the recent timestamps for NO₂, O₃ and PM10 suggest timely reporting, the outdated NO entry highlights an inconsistency in freshness across the measured suite. Users should keep in mind that conditions can differ throughout Prachatice and that the available data represent snapshots rather than continuous monitoring.

The data shown for Prachatice is based on three valid measurements and was updated within 3 days (last refresh: 2026‑02‑10T14:00:00+00:00). This snapshot reflects conditions at the time of sampling; air quality can differ across neighbourhoods and change throughout the day, so values may not represent every location or moment in the city.
