Air quality today

The air quality in Norrköping today falls into the Moderate category according to OpenAQ data. The primary pollutant identified is PM2.5 (fine particles). Measurements show a PM2.5 reference value of 10.021 and a PM10 reference value of 14.663, based on twelve valid observations.

These figures reflect the current state of particulate matter in the city without implying any trend or cause. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

What the data includes

The air‑quality feed for Norrköping includes three measured pollutants – nitrogen dioxide (NO2), fine particulate matter (PM2.5) and coarse particulate matter (PM10). Data come from a total of three monitoring rows, each representing a separate sensor location; all three rows are currently active, but one row is flagged as “unknown” in terms of its freshness status. The most recent measurements for every pollutant were recorded on 2026‑02‑10 at 18:00 UTC, so the newest values are less than a week old.

Across the three stations the observed concentrations span modest ranges. For PM2.5 the lowest reading is about 5.1 µg/m³ and the highest reaches 10.0 µg/m³, with a median of roughly 7.2 µg/m³; the 10th‑percentile sits near 5.3 µg/m³ while the 90th‑percentile approaches 10.0 µg/m³. NO2 shows a broader spread, from around 14.3 µg/m³ up to 51.5 µg/m³, median 33.5 µg/m³, with the lower decile at about 14.7 µg/m³ and the upper decile near 51.5 µg/m³. PM10 values range from roughly 8.0 µg/m³ to 14.7 µg/m³, median 11.2 µg/m³, with the 10th‑percentile at about 8.1 µg/m³ and the 90th‑percentile close to 14.5 µg/m³.

Because only three rows contribute data, spatial coverage is limited; conditions can differ across neighborhoods that are not directly represented by these sensors. While the latest timestamps are recent, one row’s freshness remains unknown, meaning a portion of the dataset may not reflect current levels. Users should keep in mind that the figures shown represent point measurements at specific sites rather than a city‑wide average.

Data notes

The data shown for Norrköping is based on twelve valid measurements and was refreshed within three days, with the most recent update recorded at 2026‑02‑10 18:00 UTC. This snapshot reflects conditions captured by the monitoring network at that time; however, air quality can vary across different neighbourhoods and change throughout the day, so local values may differ from those presented here.
