What the data includes

The air‑quality record for Linköping currently includes data from three monitoring sites and a total of ten individual measurement rows. The dataset contains the three common urban pollutants that OpenAQ reports for this city: nitrogen dioxide (NO₂), fine particulate matter (PM2.5) and coarse particulate matter (PM10). Freshness varies across the record: six of the rows were updated within the last seven days, while three are older than thirty days and one has an unknown timestamp. For each pollutant the most recent reading comes from the same location – Linköping Hamngatan 10 – with a last‑updated time of 2026‑02‑10 18:00 UTC.

PM2.5 values in the city range from a minimum of 0.0 µg/m³ to a maximum of 10.14 µg/m³, with a median around 6.63 µg/m³ and the central 80 % of observations falling between roughly 1.56 µg/m³ (10th percentile) and 9.52 µg/m³ (90th percentile). NO₂ shows a broader spread: concentrations run from 26.37 µg/m³ up to 80.66 µg/m³, the median sits near 50.03 µg/m³, and the inter‑decile range is about 31.10 µg/m³ at the low end to 74.53 µg/m³ at the high end. PM10 measurements are comparatively tight, with a minimum of 10.55 µg/m³, a maximum of 31.81 µg/m³, a median of 13.1 µg/m³ and most values clustered between 11.06 µg/m³ (10th percentile) and 28.07 µg/m³ (90th percentile).

Because the dataset contains only three stations, spatial coverage is limited; conditions can differ across neighbourhoods and times that are not captured by the current rows. Moreover, while half of the observations are recent, a notable portion – four out of ten rows – are either older than a month or lack a clear timestamp, which means the picture of Linköping’s air quality may be incomplete for periods beyond the last week.

Data notes

The data shown are based on six valid measurements and were refreshed recently, having been updated within three days (last update: 2026‑02‑10 18:00 UTC). These values provide a snapshot of current conditions but air quality can differ across neighbourhoods and change throughout the day, so local variations may not be captured in this summary.
