Air quality today
The air quality in Sarpsborg is currently classified as Moderate. The primary pollutant identified is PM2.5, with a measured concentration of 17.13 µg/m³. In addition, the PM10 level stands at 20.17 µg/m³ based on four valid observations.
Data is shown via OpenAQ. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.
Latest sensor values
PM categories follow US EPA AQI breakpoints, shown here as an estimate derived from the latest valid measurements (this project does not compute EPA NowCast/24-hour AQI yet).
What the data includes
The air‑quality record for Sarpsborg currently draws on four monitoring stations that together report on nitrogen dioxide, particulate matter ≤ 10 µm, particulate matter ≤ 2.5 µm and sulfur dioxide. All of the latest observations were uploaded on 2026-02-10 at 18:00 UTC, so the dataset is uniformly fresh within the past week.
For NO₂ the single reported value is 41.4045639 µg/m³ measured at the Alvim site; the same concentration appears as the minimum, median and maximum, indicating that only one recent reading is available for this pollutant. PM10 and PM2.5 show a similar pattern, with values of 20.1675262 µg/m³ and 17.1257229 µg/m³ respectively, both also recorded at Alvim on the same timestamp and each representing the sole data point in their series. Sulfur dioxide is reported from a different location, Vollgata, at 1.902837 µg/m³, again with identical min‑med‑max figures.
Because every pollutant column contains just one recent measurement, there is no observable spread or variability within the city’s current dataset; the range for each contaminant collapses to a single point. The coverage across pollutants is uneven in terms of geographic representation – three of the four readings come from Alvim while SO₂ originates at Vollgata – and the overall station count (four rows) limits the ability to capture spatial differences throughout Sarpsborg. While the timestamps are all up‑to‑date, the paucity of multiple observations means that short‑term fluctuations or neighborhood‑level contrasts cannot be discerned from this snapshot.

Data notes
The data shown for Sarpsborg is based on four valid measurements and was updated within 3 days, with the latest reading recorded at 2026‑02‑10T18:00:00+00:00. This snapshot reflects conditions at a specific time and place; air quality can differ across neighborhoods and change throughout the day, so values may not represent every location or moment in the city.
