LTER site Oberes Stubachtal is a long-range research site with a main focus on the measurement of the annual mass balance of the Stubacher Sonnblickkees (SSK) and processes of different glaciers, going along with water budget estimations within the catchment area of the dam lakes Weißsee and Tauernmoos that are controlled by the Austrian Federal Railways (ÖBB) and can gives you more Information about the catchment hydrology. Regular observations and systematic studies had begun with measuring the glacial length in 1960 by the brothers Heinz and Werner Slupetzky. The Massbalance of SSK is measured since 1963 and indirect back calculated till 1946. The Glaciers are photogrammetric mapped since 1963. Additionally the lake “Unterer Eisbodensee”, originated in the 1980s, is monitored with temperature, waterlevel and runoff by the Hydrographical Service of Salzburg since 2006. In the center of this researchsite is the meteorological station Rudolfshütte operated by the ZAMG since 1962. The Rudolfshütte is also a Mountain Hotel and can be use as a Basecamp. Since the year 2004 there are some TLS measurement for the generation of high resolution DTMs of the end of the glacier tongue and glacier forefield of the Odenwinkelkees and of the sourounding area of the lake “Oberer Eisbodensee”.
