Simulated ice thickness, supraglacial debris thickness and subglacial topography for Khumbu Glacier, Nepal, using the iSOSIA ice-flow model - VERSION 2.0

Simulated ice thickness (ice, metres, 100 m grid spacing) and supraglacial debris thickness (debris, metres, 100 m grid spacing) for Khumbu Glacier, Nepal, produced using the iSOSIA ice-flow model presented in Rowan et al. (2021; Journal of Geophysical Research-Earth Surface). The model domains used for the entire glacier and active glacier simulations (metres above sea level, 100 m grid spacing), and the present-day ice thickness estimate (metres, 30 m grid spacing) used to create the subglacial topography are included. The files contained in this collection present the outputs from three experiments carried out in Rowan et al. (2021; Journal of Geophysical Research-Earth Surface): 1. Simulation with a continuous debris layer, where h0 = 0.23 m and dT = 1.5 degC, showing the effect of change in mean annual air temperature to the present day (2015 CE) from 1.5 degC relative to the Little Ice Age 2. Simulation with a discontinuous debris layer, where h0 = 0.94 m and dT = 1.5 degC 3. Simulation with a discontinuous debris layer of the active glacier, where h0 = 0.94 m and dT = 1.5 degC The subglacial DEMs used for the model domains for the entire glacier and the active glacier, and the present-day (2015 CE) ice thickness estimated by Rowan et al. (2015, EPSL) to create the subglacial topography are also included (3 files).
