Abstract

The Alpine glaciers are sensitive to climate fluctuation, and glacier mass balance may be used as a proxy indicator of the regional climate change impacts. An indirect methodology is presented for determining the distribution of mass balance at high spatial resolution using remote sensing and ground stakes measurements. The method is based on the snowline determination as a proxy of the equilibrium line altitude (ELA) and the key of the transfer is the activity coefficient (db/dz) for the annual mass balance calculation. Three outlet glaciers well suited in the French Alps (ground stakes) were selected to evaluate the accuracy of the method for a short period (7 cycles) and extended for a longest period (15 cycles) for a glacier with limited ground measurements. The computed distribution of mass-balance compares well (R2=0.90) with mass-balance measurements made at stakes installed along the glacier centre line for the short period.
