This dataset contains frontal ablation estimates for 49 tidewater glaciers in Greenland which have been calculated using the following open source remote sensing data TermPicks Terminus delineations (Goliber and Black, 2021). Satellite image (for manual delineation of fjord walls). Glacier velocity (code will automatically download ITS_LIVE velocities ~15 GB) Two Digital Elevation Models (preferably ArcticDEM and AeroDEM; Porter et al., 2018, Korsgaard et al., 2016) Surface change rate (Khan, 2017) Bedrock Topography (BedMachine v4; Morlighem et al., 2017, 2021). Solid Ice Discharge (Mankoff, 2019) The dataset contains the following variables for each tidewater glacier: tbounds - boundaries of time intervals on which output data defined t - midpoint of time intervals on which output data defined D - discharge during time intervals [GT/yr] TMC - terminus mass change during time intervals [GT/yr] FA - frontal ablation during time intervals [GT/yr] D0 - discharge masking out interpolated values [GT/yr] TMC0 - ...
