Terminus Ablation Rates for the Glaciers in Kalaallit Nunaat (Greenland)

This is a the first release of the code for calculating terminus (frontal) ablation for the glaciers. We compiled datasets of terminus position, discharge, and surface and bed elevation from various sources. Glacier terminus positions were obtained from two primary sources: TermPicks (Goliber et al., 2022) and CALFIN (Cheng et al., 2021), with additional terminus traces manually added using GEEDit (Lea, 2018 ). Ice discharge, estimated as the rate of ice flowing through a flux gate towards the terminus, was obtained from (Mankoff et al., 2021). Surface elevations from ArcticDEM strips (Porter et al., 2022) and the AeroDEM (Korsgaard, 2021) and bed elevations from BedMachine 5 (Morlighem et al.,2022) were used to estimate the glacier thickness within each terminus area polygon.
