  abstract = {{M}easuring surface mass-balance in the accumulation areas of glaciers is challenging because of the high spatial variability of snow accumulation and the difficulty of conducting annual field glaciological measurements. {H}ere, we propose a method that can solve both these problems for many locations. {G}round-penetrating radar measurements and firn cores extracted from a site in the {F}rench {A}lps were first used to reconstruct the topography of a buried end-of-summer snow horizon from a past year. {U}sing these data and surface elevation observations from {L}i{DAR} and {G}lobal {N}avigation {S}atellite {S}ystem instruments, we calculated the submergence velocities over the period between the buried horizon and more recent surface elevation observations. {T}he differences between the changes in surface elevation and the submergence velocities were then used to calculate the annual surface mass-balances with an accuracy of +/- 0.34 m w.e. {A}ssuming that the submergence velocities remain stable over several years, the surface mass-balance can be reconstructed for subsequent years from the differences in surface elevation alone. {A}s opposed to the glaciological method that requires substantial fieldwork year after year to provide only point observations, this method, once submergence velocities have been calculated, requires only remote-sensing data to provide spatially distributed annual mass-balances in accumulation areas.},
