  abstract = {{B}ecause of its nearly global coverage, the {S}huttle {R}adar {T}opographic {M}ission ({SRTM}) topography is a promising data set for estimating mountain glacier volume changes. {B}ut, first, its absolute accuracy must be thoroughly investigated in a glacial environment. {W}e use topographic data available in the {F}rench {A}lps to assess the usefulness of {SRTM} for the monitoring of glacier volume variations. {W}e observe clear biases with altitude both on ice-free and glacier-covered areas. {A}t high altitudes, {SRTM} elevations are underestimated by up to 10 m. {T}hese biases can have a significant impact on any estimate of glacier volume changes. {I}f {SRTM} is the most recent of the two compared topographies, the volume loss is overestimated (and vice versa). {W}e cannot conclude definitively on the origin of these biases and whether they affect all high-mountain areas but our findings invite reconsideration of previous estimates of glacier wastage based on {SRTM}.},
