The high volume of air traffic today would be unthinkable without precise knowledge of the current weather situation. To ensure that planes are able to take off, MeteoSwiss employees monitor the weather conditions at the airports in Zurich and Geneva around the clock. As well as visual observations, which still remain important, a range of specific measuring devices is used. These include ceilometers for determining cloud layers, transmissometers for measuring visibility, and various sensors for determining the current weather. In addition to the international airports in Geneva and Kloten, these instruments are also used at the eight regional airports in Altenrhein, Bern-Belp, Buochs, Grenchen, Les Eplatures, Lugano, Samedan and Sion. The information collected by these instruments is used to create reports for pilots and air traffic control.

Aviation weather and aviation products

MeteoSwiss also uses the multitude of current weather data available to offer tailored aviation weather data for airlines, light aircraft, gliders, balloonists and hand-gliders.

Standardisation and certification

The services provided in the area of aviation meteorology are strictly standardised and regulated by national and international authorities and organisations. In 2006, MeteoSwiss was certified by the Federal Office for Civil Aviation (BAZL) for its aviation weather services in accordance with the SES (Single European Sky) regulations; this certification was renewed in 2012.
