Aarhus University is in charge of national monitoring of air quality in Denmark. Monitoring takes place through a network of monitoring stations, supplemented by modelling. Below you will find an overview of our many pages on results of measurements.

The present web pages are maintained by AU’s Department of Environmental Science. The department was established in 2011 by a merger of three research departments at the former National Environmental Research Institute (NERI).

The tasks formerly undertaken by by NERI are now dealt with by DCE - Danish Centre for Environment and Energy at Aarhus University in cooperation with the Department of Environmental Science and other departments at Aarhus University. 

On-line data (in Danish)

Here is access to recent measurement results from today and the previous week/month. Data are usually updated every hour during daytime. (For components measured with automatic instrumentation).

Map of monitoring stations

From the map there is access to information about the individual stations and the air pollution components measured at each station.

Monitoring results on an annual and multi-annual basis

Results are presented for a large number of air pollution components in the form of tables (a table for each year) and graphs (showing the trends over many years).

Database: Retrieve air quality data

Here you can generate graphs or tables with results of measurements of various pollutants. The database contains results aggregated on a yearly basis.

Description of the monitoring programme

Aarhus Universitet is responsible for a nation-wide network of air quality monitoring stations in Denmark. Until 2010 there were two networks (the urban ”LMP” network and a background network). These have been replaced by a single unified network.

Annual monitoring reports

DCE – Danish Centre for Environment and Energy at Aarhus University publishes annual reports with results from the monitoring programme. Many of these reports are in English, and they provide a good overview of the situation in Denmark.

Monitoring results from other countries
