Air quality today

The air quality today in Sollentuna kommun is classified as Moderate. The primary pollutant identified is PM2.5 (fine particles). Measurements show a PM2.5 reference value of 11.16 µg/m³ and a PM10 reference value of 16.41 µg/m³, based on 19 valid observations.

These figures reflect the current assessment provided through OpenAQ data. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

What the data includes

The OpenAQ feed for Sollentuna kommun contains data from six monitoring stations spread across 26 individual rows. For the city you can find readings of nitrogen dioxide (NO₂), particulate matter in three size fractions (PM₁, PM₂·₅ and PM₁₀), relative humidity, temperature and particle count (UM003). Overall the dataset is fairly current: nineteen of the rows have measurements taken within the last seven days, while seven rows are older than that. The most recent timestamps range from 2026‑02‑10 18:00 UTC for PM₁₀ to 2026‑02‑10 19:00 UTC for PM₂·₅, PM₁, relative humidity, temperature and UM003; the NO₂ data is older, last updated on 2020‑12‑11 14:00 UTC.

Across the recent measurements the concentrations show a modest spread. For PM₁₀ the values observed this week range from about 5.4 µg/m³ to 22.7 µg/m³ with a median of roughly 10.2 µg/m³, while the 10th‑percentile sits near 7.7 µg/m³ and the 90th‑percentile close to 17.0 µg/m³. PM₂·₅ values are lower, varying between 2.9 µg/m³ and 11.5 µg/m³, median 5.35 µg/m³, with a 10th‑percentile of about 3.9 µg/m³ and a 90th‑percentile near 11.2 µg/m³. NO₂ shows a narrower historic range from 12.4 µg/m³ to 20.1 µg/m³, median 16.2 µg/m³, but the last reading is several years old, so it may not reflect current conditions.

The other parameters are represented by single‑value entries because each station reports only one recent observation. PM₁ is recorded at 5.21 µg/m³, relative humidity at 43.1 %, temperature at 1.41 °C and particle count (UM003) at 477.25 particles/cm³, all measured at the Igelkotten site on 2026‑02‑10 19:00 UTC. Because many pollutants have only one recent data point while NO₂ is dated, the picture of air quality in Sollentuna can differ by location and time; users should keep in mind that conditions may vary outside the moments captured by these sensors.
