Air quality today

The air quality in Uppsala is classified as Good today. The primary pollutant measured is PM2.5, with a reported concentration of 6.7704 µg/m³. In addition, the level of PM10 recorded is 13.66 µg/m³, based on twelve valid measurements collected through OpenAQ.

Overall conditions meet the criteria for a Good rating according to the current assessment. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

What the data includes

The dataset for Uppsala contains measurements of nitrogen dioxide (NO₂), particulate matter 1 µm (PM₁), PM₂.₅, PM₁₀, relative humidity, temperature and particle count (UM003). In total there are 27 rows of data coming from six monitoring stations across the city. The most recent observations for the three air‑quality pollutants – NO₂, PM₂.₅ and PM₁₀ – were recorded on 2026‑02‑10 18:00 UTC, while the supporting variables (PM₁, relative humidity, temperature and UM003) are only available from a single older record dated 2025‑04‑13 10:00 UTC.

For the three primary pollutants the values show a modest spread. PM₁₀ ranges from 0 µg/m³ up to about 19 µg/m³ with a median of roughly 11.6 µg/m³; PM₂.₅ varies between 3.9 and 10.1 µg/m³, median 5.6 µg/m³; NO₂ spans 7.8 to 49.1 µg/m³, median 24.4 µg/m³. The tenth‑percentile values are close to the minima (around 2.7 µg/m³ for PM₁₀, 4.1 µg/m³ for PM₂.₅ and 7.8 µg/m³ for NO₂) while the ninetieth percentiles sit near the upper ends of each range, indicating that most recent readings are clustered toward the higher side of the observed distribution.

The coverage is uneven: three pollutants have six recent rows each, but the other four variables rely on a single old entry. Consequently, many city locations and times are not represented in the current snapshot, and conditions can differ across neighborhoods and throughout the day. Users should keep in mind that the available data provide only a limited picture of Uppsala’s air quality at this moment.

Data notes

The dataset for Uppsala includes twelve valid measurements and is refreshed regularly, having been updated within three days (last update 2026‑02‑10T18:00:00+00:00). These figures represent the most recent monitoring data available for the city. Please note that air quality can differ across neighborhoods and change throughout the day, so this snapshot may not reflect conditions at every location or time.
