This dataset contains frontal ablation estimates for 49 tidewater glaciers in Greenland in shapefile, geopackage and NetCDF format, with the variables being defined as follows: F – Three-monthly frontal ablation estimates during time intervals [Gt/d] Max_Error_F – Maximum error over total time period [Gt/d] Date – Midpoint of time intervals on which output data defined [yyyy-mm-dd] D – Discharge during time intervals [Gt/d] D_Error - Discharge error for time interval [Gt/d] TMC – Terminus mass change (dM/dt) during time intervals [Gt/d] TMC - Terminus mass change error during time interval [Gt/d] The frontal ablation estimates 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 ...
