  abstract = {{A}pproximately 25% of the glacierized area in the {E}verest region is covered by debris, yet the surface mass balance of debris-covered portions of these glaciers has not been measured directly. {I}n this study, ground-based measurements of surface elevation and ice depth are combined with terrestrial photogrammetry, unmanned aerial vehicle ({UAV}) and satellite elevation models to derive the surface mass balance of the debris-covered tongue of {C}hangri {N}up {G}lacier, located in the {E}verest region. {O}ver the debris-covered tongue, the mean elevation change between 2011 and 2015 is -0.93 m year(-1) or 0.84 m water equivalent per year (w.e.a(-1)). {T}he mean emergence velocity over this region, estimated from the total ice flux through a cross section immediately above the debris-covered zone, is +0.37 m w.e.a(-1). {T}he debris-covered portion of the glacier thus has an areaaveraged mass balance of -1.21 +/- 0.2 m w.e.a(-1) between 5240 and 5525 m above sea level (m a.s.l.). {S}urface mass balances observed on nearby debris-free glaciers suggest that the ablation is strongly reduced (by ca. 1.8 m w.e.a(-1) /by the debris cover. {T}he insulating effect of the debris cover has a larger effect on total mass loss than the enhanced ice ablation due to supraglacial ponds and exposed ice cliffs. {T}his finding contradicts earlier geodetic studies and should be considered for modelling the future evolution of debris-covered glaciers.},
