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 Târnăveni includes three measured pollutants – nitrogen dioxide (NO₂), carbon monoxide (CO) and particulate matter ≤ 10 µm (PM₁₀). Data are drawn from six measurement rows in total, with four rows classified as recent and two as older entries. For NO₂ and PM₁₀ the most recent readings were recorded on 2026‑02‑10 at 19:00 UTC, so these values are fresh (updated within the last seven days). The CO reading is much older, last updated on 2025‑06‑06 at 10:00 UTC, and is flagged as old data.
The NO₂ values show a very narrow spread: the minimum recorded concentration is 13.4508 µg/m³, the median is 13.5525 µg/m³ and the maximum is 13.6541 µg/m³, with the 10th‑percentile at 13.4711 µg/m³ and the 90th‑percentile at 13.6338 µg/m³. This indicates that recent NO₂ measurements are tightly clustered around a typical level of roughly 13.5 µg/m³. PM₁₀ has only one recent entry, giving a single value of 17.28488 µg/m³; there is no observed variation for this pollutant in the current dataset. The CO reading is recorded as –1000.0 µg/m³, which reflects an invalid or placeholder measurement rather than a true concentration.
Overall, the data coverage is uneven: NO₂ and PM₁₀ have up‑to‑date observations from multiple recent rows, while CO relies on a single outdated entry that does not provide usable information. Because the dataset contains only a handful of rows and some values are missing or stale, the snapshot may not capture the full spatial or temporal variability of air quality across Târnăveni.
