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. The measurements are supplemented with a wide array of additional observations, ranging from manual recording of cloud cover and vegetation development, to measurements of fine particulate matter, through to a network of cameras that covers all major sections of terrain and mountain passes in Switzerland.
