An automatic weather station in the heart of the Mont-Blanc mountains

Since January 2014, the most popular French mountains have had their own automatic weather station. It transmits valuable information in real time to mountain sports enthusiasts and professionals, which is useful when planning a trek on foot or on skis. The Petzl Foundation helps maintain it.

In December 2013, a weather station was set up above the Requin refuge at an altitude of 2,800 meters. Ideally placed in the heart of the Mont Blanc range, it measures temperature, air humidity, solar radiation, snow depth, wind speed and wind direction. The data is updated every 15 minutes and transmitted via the mobile phone network, which allows users to monitor weather conditions in real time. An automatic camera takes a high definition shot of the Glacier du Géant every 30 minutes. This information is extremely useful for climbers, mountain guides and skiers descending the Vallée Blanche. The data is available free of charge on the Eau, Neige et Glace Foundation's website.

Detailed open source data is also available on request for research purposes and in this way, this weather station further strengthens the links between mountain sports and scientific research. The Petzl Foundation contributes to funding of its maintenance.
