  abstract = {{M}ass losses originating from supraglacial ice cliffs at the lower tongues of debris-covered glaciers are a potentially large component of the mass balance, but have rarely been quantified. {I}n this study, we develop a method to estimate ice cliff volume losses based on high-resolution topographic data derived from terrestrial and aerial photogrammetry. {W}e apply our method to six cliffs monitored in {M}ay and {O}ctober 2013 and 2014 using four different topographic datasets collected over the debris-covered {L}irung {G}lacier of the {N}epalese {H}imalayas. {D}uring the monsoon, the cliff mean backwasting rate was relatively consistent in 2013 (3.8 +/- 0.3 cm w.e. d(-1)) and more heterogeneous among cliffs in 2014 (3.1 +/- 0.7 cm w.e. d(-1)), and the geometric variations between cliffs are larger. {T}heir mean backwasting rate is significantly lower in winter ({O}ctober 2013-{M}ay 2014), at 1.0 +/- 0.3 cm w.e. d(-1). {T}hese results are consistent with estimates of cliff ablation from an energy-balance model developed in a previous study. {T}he ice cliffs lose mass at rates six times higher than estimates of glacier-wide melt under debris, which seems to confirm that ice cliffs provide a large contribution to total glacier melt.},
