MeteoSwiss operates a comprehensive automatic monitoring network at ground level. It also uses various other monitoring and observation networks which, for example, serve to improve aviation safety and collect data on health-related and climatic issues. The ground-level monitoring networks are supplemented by monitoring networks for the recording of atmospheric conditions. The requirements relating to the collection of meteorological measurement data are derived from the Federal Law on Meteorology and Climatology (MetG). MeteoSwiss creates monitoring concepts which take account of the requirements of other Federal Offices. These concepts define which parameters are measured and for what purpose, as well as where the measurements are taken and using what system.
