Manual precipitation monitoring network
In addition to its automatic precipitation measurements, MeteoSwiss also operates a manual precipitation monitoring network. Measurements are taken here once a day and transmitted to MeteoSwiss via SMS. The network comprises 243 locations (190 stations measure rainfall and snowfall, and 53 stations measure snowfall only). Due to their long-series measurements, they are of great climatological significance. In mountainous areas that are difficult to access, around 57 totalisers are used which record the volume of precipitation for an entire year.
