What the data includes

The data for Östersund includes three measured pollutants – nitrogen dioxide (NO₂), particulate matter 10 µm or smaller (PM₁₀) and fine particulate matter 2.5 µm or smaller (PM₂.₅). All values come from two monitoring stations, together providing eight recent rows of observations. The most recent update for each pollutant was recorded on 2026‑02‑10 at 18:00 UTC, so the freshest data are all within the past week.

Across the eight rows, PM₁₀ concentrations range from a low of 0.9 µg/m³ to a high of 2.7 µg/m³, with a median value of 0.9 µg/m³ and the 10th‑percentile also at 0.9 µg/m³, indicating that most recent readings cluster near the lower end of the observed spread. PM₂.₅ shows a slightly broader distribution: values run from 0.6 to 1.6 µg/m³, median 0.7 µg/m³, with the 10th‑percentile at 0.62 and the 90th‑percentile at 1.42 µg/m³. NO₂ exhibits a higher absolute range, from 14.6 to 34.6 µg/m³, median 24.6 µg/m³, and percentiles of 16.6 (10th) and 32.6 (90th), suggesting more variability in the nitrogen dioxide measurements.

Because only two stations contribute data, spatial coverage is limited; conditions can differ across neighborhoods that are not directly represented by these sensors. Nevertheless, all three pollutants have recent observations within the last seven days, providing a current snapshot of air quality at the monitored locations.
