National Air Pollution Monitoring Network NABEL: stations (Federal Office for the Environment FOEN)
The National Air Pollution Monitoring Network (NABEL) monitors air quality at 16 different locations in Switzerland. The monitoring stations are spread over the entire country and measure pollution levels in different types of situations (e.g. streets in city centres, residential areas, rural sites). The NABEL air quality monitoring stations yield different results depending on the type of location. Comparisons of air quality are therefore only possible among stations covering similar location types, not among geographic areas per se.
