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 the Municipality of Nea Smyrni contains measurements from five monitoring rows, each reporting a single pollutant at the NEA SMIRNI station. The available pollutants are carbon monoxide (CO), nitrogen oxide (NO), nitrogen dioxide (NO2), ozone (O3) and particulate matter ≤10 µm (PM10). All values are expressed in micrograms per cubic metre (µg/m³).
The most recent data timestamps are from 2026‑02‑10 19:00 UTC for CO, NO2, O3 and PM10, indicating that the majority of the record is up to date within the last three days. The NO measurement is older, with its latest entry dated 2024‑03‑11 12:00 UTC, which the source flags as “old data.” Because each pollutant appears in only one row, there is no spatial spread across the city; the figures represent a single monitoring point rather than a network of stations.
All five pollutants show identical minimum, median and maximum values, meaning that for this period each metric is effectively a single observation. CO registers at 1000.0 µg/m³, NO at 1.0 µg/m³, NO2 at 36.0 µg/m³, O3 at 31.0 µg/m³ and PM10 at 15.0 µg/m³. The lack of variability (p10 and p90 equal the median) suggests that the dataset does not capture fluctuations over time or across locations within Nea Smyrni. Consequently, while the data are recent for most pollutants, the limited number of rows and the single‑site coverage mean that city‑wide conditions may differ from these point measurements.
