How to read it

AQI, PM2.5 and PM10 describe different parts of the air picture

The AQI value is an index intended to summarize current air conditions, while PM2.5 and PM10 are particulate-matter measurements. They should not be treated as interchangeable values or as a permanent rating of Copenhagen.

Air conditions can change with weather, season, local activity and measurement timing. Placeivo therefore keeps the observation date and latest check visible and avoids converting a single reading into a broad city health or quality-of-life verdict.

Recent trend

Copenhagen air quality over the last 7 days

Daily values below are averages calculated from hourly European AQI, PM2.5 and PM10 observations. This recent window shows short-term variation; it is not a long-term annual air-quality rating.

Evidence interpretation

What the latest Copenhagen air readings say

The latest stored measurements report a European AQI of 19, PM2.5 of 3.2 µg/m³ and PM10 of 7.1 µg/m³.

These are time-specific environmental measurements. They are useful as a current snapshot, but a single reading cannot establish typical annual air quality or a permanent health ranking for Copenhagen.

Evidence & methodology

Where these air quality figures come from

Placeivo keeps source attribution, the date represented by the observation, the latest verification check and confidence metadata separate. This makes it possible to inspect the evidence instead of relying on an unexplained score.
