a Comparison of snowfall (blue lines) and snowmelt (red lines) per elevation band for selected months, with the equilibrium-line altitude (ELA, grey line), the median modelled value across all glaciers. Shaded areas represent mass gain (blue) and mass loss (red). b Catchment (black line) and glacier (green line) hypsometry. c Total melt volume per elevation band for on- (blue) and off- (red) glacier snow melt and ice melt (green), the solid lines are the average over all months, with small dashes representing mean total melt in January and large dashes representing total melt in July. d Average per cell on (blue small dashes) and off (red big dashes) glacier snow water equivalent (SWE), with the shading representing the seasonal range (blue for on-glacier and red off-glacier), and on the top x-axis the percentage of time with snow cover at a range of modelled points across the catchment (grey dots). All values are based on model outputs averaged over the 2008−2018 analysis period.
