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 Děčín draws from a single monitoring station, so each pollutant is represented by one data row. The dataset includes four measured compounds: nitrogen monoxide (NO) at 4.1 µg/m³, nitrogen dioxide (NO₂) at 10.1 µg/m³, particulate matter up to 10 µm (PM₁₀) at 17.5 µg/m³ and fine particles up to 2.5 µm (PM₂.₅) at 10.6 µg/m³. All values are reported in micrograms per cubic metre.
The timestamps show a mixed picture of freshness. The NO measurement is the oldest entry, last updated on 2024‑03‑11 10:00 UTC, while the other three pollutants were refreshed more recently on 2026‑02‑10 (NO₂ at 12:00 UTC and both PM₁₀ and PM₂.₅ at 14:00 UTC). Because only one station supplies data, there is no variation in spatial coverage across the city; any local differences in air quality are not captured by this set.
Statistically, each pollutant’s minimum, median and maximum values are identical, indicating that only a single observation is available for each. Consequently, the dataset cannot reveal any range or trend beyond these point figures. The overall freshness score reflects that three of the four rows fall into the “updated within 3 days” category, while one row remains older than a year. Users should keep in mind that conditions can change across neighborhoods and over time, and the current snapshot represents only the most recent reading from the lone Děčín sensor.
