What the data includes

The air‑quality record for Imatra includes three measured pollutants – nitrogen dioxide (NO2), particulate matter 10 µm or smaller (PM10) and sulfur dioxide (SO2). Data come from six rows in total, but the coverage is uneven: three rows report NO2, two rows report PM10 and only a single row provides SO2 values. All of the latest updates were recorded on 2026‑02‑10 at 18:00 UTC, so the most recent measurements are fresh, having been updated within the last three days.

For NO2 the observed concentrations range from about 5.40 µg/m³ up to a maximum of 10.79 µg/m³, with a median value near 7.87 µg/m³ and the 10th‑percentile at 5.89 µg/m³. This indicates that most recent readings cluster around eight micrograms per cubic metre, while occasional higher values approach eleven. PM10 shows a narrower spread: values run from roughly 4.48 to 6.52 µg/m³, the median sits at 5.50 µg/m³ and the 90th‑percentile is 6.31 µg/m³, suggesting relatively consistent particulate levels across the two reporting stations. SO2 is represented by a single measurement of 1.06 µg/m³ from Rautionkylä, with no variation because only one row contributes data.

Overall, the dataset provides recent information for all three pollutants but the depth differs: NO2 and PM10 each have multiple observations allowing an assessment of range and typical values, whereas SO2 is limited to a single point. Because the station count varies by pollutant, conditions in Imatra can differ across locations and times, and the available data reflect only the spots where sensors are installed.

Data notes

The data shown for Imatra reflects four valid measurements and is updated within 3 days, with the latest values recorded at 2026‑02‑10T18:00:00+00:00. This snapshot provides a current view of city‑wide air quality but conditions can differ across neighborhoods and change throughout the day, so local variations may not be captured in these figures.
