MeteoSwiss collects meteorological data at ground level and in the atmosphere. Highly specialised instruments are used for taking the measurements.
MeteoSwiss operates a network of land-based weather stations where current weather and climate data are automatically recorded. It covers all parts of the country and all altitude levels. These range from the manual recording of cloud cover and vegetation development to particulate matter, soil moisture and ozone measurements and a camera network that records the most important terrain and mountain passes in Switzerland.
