Winter Season



The Swiss National Basic Climatological Network (Swiss NBCN) connects the major ground-based stations within the MeteoSwiss monitoring network. It consists of 29 climate monitoring stations and 46 precipitation stations. The measurement series available in digital form for temperature, precipitation and hours of sunshine date back, in some cases, to the mid-nineteenth century.

MeteoSwiss has been conducting systematic measurements of climate parameters at ground level in all parts of the country since 1864. Certain monitoring stations in this network are run with particular precision and are the bedrock for research into climate change. The particular ground-based monitoring stations in the network that are the most important from a climatological perspective together form the Swiss National Basic Climatological Network (Swiss NBCN). These provide the basis for long-term, continual high-quality climate data series. MeteoSwiss
