AMD - DIF Record(s) USAP-1933764_1 Abstract This dataset contains observed and modeled conditions along the Crane Glacier centerline for ~1994—2100. Observations include centerline (cl) coordinates, downscaled RACMO climate variables (runoff, snowfall, snowmelt, and surface mass balance), bed elevations (b), surface elevations (h), glacier width (W), calving front positions (xcf), and surface speeds (U) when available for the 1994—2019 period. Modeling results include glacier centerline geometry, speed, glacier mass discharge (Q_gl), and calving front and grounding line positions (x_cf and x_gl) under different future climate scenarios with varying surface mass balance (SMB), ocean thermal forcing (FT), SMB with potential feedbacks associated with enhanced surface melt water discharge and plume strengthening (SMB_enh), and concurrent SMB_enh and FT perturbations (SMB_enh_FT). Data are in “.mat” format, which can be read using MATLAB’s “load” function or using Python with the Scipy “scipy.io.loadmat” function.
