This corrected version was uploaded on 2018-02-15. In the past three periods, 2014/2015, 2015/2016 and 2016/2017, in the extrapolation of mass balance to total glacier area, zones with b=0 mm w.e. have been defined. In the current analysis, these areas have been changed to ablation zones with the lowest possible ablation of -25 mm w.e., to maintain the records consistency. Therefore, small changes have been applied to the mass balance data of the three years 2014/2015, 2015/2016 and 2016/2017 so that older versions of the time series and reports can slightly deviate.Changes affect the altitude levels 2925 to 2975 for the period 2014/2015, 2975 to 3175 for the period 2015/2016 and 2875 to 2975 for 2016/17.
