The individual measurement methods are aimed at different components of air pollution. Some measurements are made with instruments that immediately deliver an analysis. Other measurements are based on long-term collection and subsequent analysis in the laboratory.
Some measurements are made with continuously recording instruments, ie. analytical instruments that perform the analysis immediately and deliver a result immediately. Other measurement methods are based on collection and subsequent analysis in the laboratory.
At measuring stations with continuously recording instruments, the air is sucked in and an analysis is made immediately which is stored on a PC at the station. The results are transmitted via telephone or internet to the central data collection unit, which is located at DCE in Roskilde.
Measurement methods for the individual substances and particles can be found in the menu to the right.
