Air quality today

The air quality in Kalmar is classified as Good today. The primary pollutant measured is PM2.5 (fine particles). Data from six valid measurements show a PM2.5 reference value of 8.0 µg/m³ and a PM10 reference value of 10.2 µg/m³, indicating that concentrations are within the limits associated with this category.

These figures are provided through OpenAQ and reflect the current monitoring snapshot for Kalmar. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

What the data includes

The air‑quality data for Kalmar comes from a single monitoring site – Kalmar Södra Vägen – and includes three measured pollutants: nitrogen dioxide (NO₂), particulate matter 10 µm or smaller (PM₁₀) and fine particulate matter 2.5 µm or smaller (PM₂.₅). In total six individual rows of observations are available, all recorded at the same location, so the dataset reflects conditions at one point in the city rather than a network of stations.

The most recent values were uploaded within the last week. The NO₂ reading was last updated on 2026‑02‑10 18:00 UTC, while both PM₁₀ and PM₂.₅ were refreshed on 2026‑02‑10 17:00 UTC. For each pollutant a single measurement is shown as the current value, but the dataset also provides the minimum, median and maximum observed across the six rows. NO₂ values range from 14.9 to 14.9 µg/m³, with a median of 14.9 µg/m³, indicating no variation in this short series. PM₁₀ spans 10.2 µg/m³ at its lowest to 16.6 µg/m³ at its highest, with a median of 13.4 µg/m³; the 10th and 90th percentiles are 10.84 and 15.96 µg/m³ respectively, showing modest spread. PM₂.₅ varies between 8.0 µg/m³ and 14.6 µg/m³, median 11.3 µg/m³, with the 10th and 90th percentiles at 8.66 and 13.94 µg/m³.

Because the data originates from only one monitoring point, it captures conditions at that specific site but does not represent the full spatial diversity of air quality across Kalmar. All observations are recent, yet the limited number of rows means the reported ranges reflect a narrow time window rather than long‑term trends.

Data notes

The current dataset for Kalmar includes six valid measurements and is updated within three days, with the latest values recorded at 2026‑02‑10T18:00:00+00:00. These figures represent a snapshot of ambient conditions across the monitoring network; actual air quality can differ by specific location and time of day within the city, so individual experiences may vary from the reported averages.
