The program automatically downloads the Tête Rousse and Goûter camera every hour between 06:00 and 20:59 of UTC time (07:00 and 21:59 of CET time). Images from each camera are stored in separate folders: "tete_rousse" and "gouter". This information helps track snow conditions in the infamous Grand Couloir, allowing mountaineers to plan their Mont Blanc hike when the conditions in the couloir are optimal.
