What the data includes

The Virolahti air‑quality record contains data for five pollutants – nitrogen dioxide (NO₂), ozone (O₃), particulate matter ≤ 10 µm (PM10), particulate matter ≤ 2.5 µm (PM2.5) and sulphur dioxide (SO₂). The dataset comprises ten individual rows drawn from two monitoring sites, all of which were last refreshed on 2026‑02‑10 at 18:00 UTC, so the most recent values are no older than three days.

Across the pollutants the observed concentrations span a modest range. For NO₂ the maximum recorded value is 2.75 µg/m³ while the median sits near 0.87 µg/m³; O₃ shows a broader spread with a peak of 70.10 µg/m³ and a median of 34.55 µg/m³. PM10 reaches up to 3.23 µg/m³ (median ≈ 1.11) and PM2.5 peaks at 2.51 µg/m³ (median ≈ 0.75). SO₂ is the lowest‑level pollutant in this set, with a maximum of 1.06 µg/m³ and a median around 0.03 µg/m³. The tenth percentile values for several pollutants are negative, reflecting the way the raw sensor output is processed before reporting.

All five contaminants have complete recent coverage; there are no rows flagged as old or unknown in this snapshot. Because the data come from only two stations, spatial variation within Virolahti cannot be captured in detail, and conditions may differ elsewhere in the municipality. Nonetheless, the current record provides a contemporaneous picture of ambient levels for each listed pollutant at the monitored locations.
