The air quality today in Køge Municipality is classified as USG. The primary pollutant identified is PM2.5 (fine particles). Measurements show a PM2.5 concentration of 46.10 µg/m³ based on five valid observations recorded via OpenAQ.
Overall, the data indicate that fine particulate matter is the dominant factor influencing air quality in the area at this time. 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 dataset for Køge Municipality contains five recent observations collected from a single monitoring location at Lille Skensved. All available pollutants are represented: PM1, PM2.5, relative humidity, temperature and the particle count UM003. Each parameter has one recorded value, all captured at the same moment on 2026‑02‑10 20:00 UTC, so the data is uniformly fresh across the board.
The measured concentrations show a very narrow spread because only one reading exists for each pollutant. PM1 registers 25.5221666653951 µg/m³ and PM2.5 records 46.10016657511394 µg/m³, while relative humidity stands at 68.89233385721842 % and temperature is 4.437999995549521 °C. The UM003 particle count is 985.8191650390623 particles/cm³. Because there is a single row per pollutant, the minimum, median and maximum values are identical, indicating no observed variability within this snapshot.
With just one sensor site, the coverage for Køge is limited; any spatial differences in air quality across the municipality cannot be captured by this dataset. The timestamps confirm that the most recent update is less than three days old, satisfying the “updated within 3 days” freshness label, but the lack of multiple stations or historical rows means trends over time are not available here. Consequently, while the current figures give a precise picture for Lille Skensved at the recorded moment, they do not reflect broader temporal or geographic changes that may occur elsewhere in Køge Municipality.

Data notes
The data shown for Køge Municipality are based on five valid measurements and were updated within 3 days (last refresh: 2026‑02‑10T20:00:00+00:00). This snapshot reflects conditions at the time of collection; air quality can differ across neighbourhoods and change throughout the day, so values may not represent every location or moment in the city.
