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 Piatra Neamț contains measurements for five pollutants – carbon monoxide (CO), nitrogen dioxide (NO₂), ozone (O₃), particulate matter 10 µm or less (PM10) and sulphur dioxide (SO₂). The information comes from seven data rows that originate at two monitoring stations, so the spatial coverage is limited to a small number of locations within the city. Freshness varies: five of the rows have been updated in the last week, while the remaining two are older than seven days. No measurements were recorded today or in the past three days.
For NO₂ the most recent value is 23.98175 µg/m³, with a minimum observed level of 5.07 µg/m³ and a maximum of 23.98 µg/m³ across the available rows; the median sits at 14.53 µg/m³ and the 10th‑90th percentile range spans roughly 7 to 22 µg/m³. Ozone shows a tighter band, ranging from 35.45 to 44.09 µg/m³, a median of 39.77 µg/m³ and a 10th‑90th percentile interval of about 36 to 43 µg/m³. PM10 is represented by a single consistent reading of 37.81628 µg/m³, while SO₂ also appears as a single value at 9.10069 µg/m³. CO data are present but all entries carry the placeholder –1000.0 µg/m³, indicating that no valid measurements are available for this pollutant.
The overall picture shows uneven coverage: NO₂ and O₃ have multiple recent observations allowing a sense of variability, whereas PM10, SO₂ and especially CO rely on single or placeholder values, limiting insight into their fluctuations. Because only two stations contribute data, conditions can differ across other parts of Piatra Neamț, and the older rows mean that some aspects of the current air quality may not be fully captured.

Data notes
The data shown for Piatra Neamț is based on four valid measurements and was refreshed recently, having been updated within three days (last update: 2026‑02‑10 19:00 UTC). While this snapshot reflects the current monitoring conditions, air quality can differ across neighborhoods and change throughout the day, so values may not represent every location or moment in the city.
