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 record for Třinec draws on six data rows collected from two monitoring stations. All four key pollutants—nitrogen dioxide (NO₂), ozone (O₃), particulate matter 10 µm or less (PM₁₀) and particulate matter 2.5 µm or less (PM₂.₅)—are represented, but the freshness of the measurements varies across them.
The most recent readings for PM₁₀ and PM₂.₅ come from the Trinec‑Kanada site and were logged on 2026‑02‑10 at 14:00 UTC, showing a maximum of 6.9 µg/m³ for PM₁₀ and 5.2 µg/m³ for PM₂.₅. Both pollutants have a narrow observed range: PM₁₀ values span from 4.6 to 6.9 µg/m³ with a median of 5.75, while PM₂.₅ ranges from 4.3 to 5.2 µg/m³ with a median of 4.75. This limited spread suggests relatively stable particulate concentrations during the recent sampling period.
In contrast, the NO₂ data are older, recorded on 2023‑02‑16 at 00:00 UTC at the same Trinec‑Kanada location, and consist of a single value of 19.5 µg/m³. Because there is only one row for this pollutant, no range or median can be derived, highlighting a gap in recent nitrogen dioxide coverage. Ozone measurements are also current, taken on 2026‑02‑10 at 14:00 UTC from the Trinec‑Kosmos site, with a solitary value of 57.1 µg/m³.
Overall, while particulate matter data are up‑to‑date and show modest variability, nitrogen dioxide information is outdated and limited to one entry, and ozone is represented by a single recent point. Consequently, the snapshot captures only part of Třinec’s air quality picture; conditions can differ across neighborhoods and over time, especially for pollutants with sparse or older records.

Data notes
The data shown reflects five valid measurements and is Updated within 3 days, with the latest reading recorded on 2026‑02‑10 at 14:00 UTC. This snapshot provides a brief overview of current conditions; however, air quality can differ across neighborhoods and change throughout the day, so values may not represent every location or moment in Třinec.
