Mass Balance Factsheet for the Griesgletscher, Alps
Griesgletscher is a temperate valley glacier located in the central Swiss Alps at the border to Italy. The glacier currently covers an area of 4.4 km2 flowing in a north-east direction from 3310 m a.s.l. down to 2430 m a.s.l (2017). The mean equilibrium line altitude is 3010 m a.s.l. Mass balance measurements started in 1961 in connection with the construction of a reservoir for hydro-power production. In the 1970s up to 80 stakes were measured. The network consists of 19 stakes today that are surveyed seasonally. Topographic maps or photogrammetrical surveys exist for 1884, 1923, 1961, 1967, 1979, 1986, 1991, 1998, 2003, 2007 and annually since 2012 (Bauder et al., 2007). Huss et al. (2009) re-analyzed and homogenized the seasonal stake data and ice volume changes for the period 1961 to present. Mass balance measurements are perfromed in the frame of the programme GLAMOS (Glacier Monitoring Switzerland, www.glamos.ch).
