Abstract

The AA. analyzed the 20th century ice volume changes for 20 glaciers in the south-eastern Swiss Alps. Using a distributed accumulation and temperature-index melt model, they derived mass balance time series in seasonal resolution from 1900. The model was calibrated using ice volume changes obtained from differentiating digital elevation models based on (i) terrestrial topographic surveys, (ii) the Shuttle Radar Topographic Mission (SRTM), and (iii) aerial photogrammetry. In-situ point measurements of annual mass balance and winter accumulation were available for some glaciers, and long-term discharge records were used for model validation. The rate of mass loss between 1900 to 2008 strongly differed between adjacent glaciers. Using a combined model for 3D glacier evolution and stream-flow runoff driven by regional climate scenarios, they generated perspectives for the 21st century
