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.

Das Ende der manuellen Beobachtungen für die Luftfahrt in Genf – zwischen menschlicher Kompetenz und technologischem Fortschritt

Vor etwa einem Jahr hat MeteoSchweiz die Beobachtungsstation am Flughafen Genf geschlossen. Vor Ort werden seither keine manuellen Beobachtungen mehr durchgeführt. Damit ging für das Regionalzentrum West von MeteoSchweiz eine Ära zu Ende, in der der Mensch eine wichtige Rolle gespielt hatte.

Disparition du métier d’observateur météo : à la croisée de l’expertise humaine et des progrès technologiques

Depuis environ une année, l’arrêt des observations humaines et la fermeture du poste d’observation à l’aéroport de Genève ont marqué la fin d’une ère au centre régional Ouest de MétéoSuisse. Dans ce blog, quelques observateurs et une observatrice partagent leur expérience de météorologues postés aux premières loges pour suivre l’évolution du temps et de la technologie.

La fine delle osservazioni manuali per l'aviazione a Ginevra, fra competenza umana e progresso tecnologico

Da circa un anno, MeteoSvizzera ha chiuso la stazione di osservazione all'aeroporto di Ginevra. Sul posto nessuno svolge più osservazioni visive manuali. Termina così un’era per il Centro regionale Ovest di MeteoSvizzera, in cui la componente umana ha svolto un ruolo di primo piano.
