What the data includes

The data set for Pori includes three measured pollutants – nitrogen dioxide (NO₂), particulate matter 10 µm or smaller (PM₁₀) and particulate matter 2.5 µm or smaller (PM₂.₅). All values come from a single monitoring location, Paanakedonkatu, so the station count is one for each pollutant. The most recent readings were recorded on 2026‑02‑10 at 18:00 UTC and are listed as “Updated within 3 days,” indicating that the data are fresh and reflect current conditions.

For NO₂ the observed values range from a low of about 33 µg/m³ to a high of roughly 48 µg/m³, with a median around 41 µg/m³. The 10th‑percentile sits near 34.5 µg/m³ and the 90th‑percentile close to 46.7 µg/m³, showing a modest spread around the central tendency. PM₁₀ values are tightly clustered: the minimum is 28.3 µg/m³, the maximum just under 30 µg/m³, and the median essentially the same at 29.1 µg/m³; the inter‑percentile range (28.5–29.8 µg/m³) confirms very little variation during the reporting period. PM₂.₅ also shows limited fluctuation, with a low of about 20.1 µg/m³, a high of 22.1 µg/m³ and a median near 21.1 µg/m³; the 10th‑percentile is 20.3 µg/m³ and the 90th‑percentile 21.9 µg/m³.

Because all three pollutants are reported from the same single site, the dataset provides a consistent snapshot for that location but does not capture spatial differences across Pori. The timestamps being recent means the figures represent the latest available conditions, yet any variation elsewhere in the city would not be reflected here.
