This repository contains data documenting ice displacements resulting from a cascade of subglacial drainage outbursts below the Northeast Greenland Ice Stream (NEGIS). The data is presented and analyzed in the manuscript: "Andersen et al. (2023) Episodic Subglacial Drainage Outbursts Below the Northeast Greenland Ice Stream " (submitted to Geophysical Research Letters). The repository contains the following: - UpliftEvents_vlosDiff_T112D.zip a collection of GeoTIFF files, each containing measurements of ice displacement anomalies for a local inferred uplift event. The displacements are measured with the DInSAR (Differential Synthetic Aperture Radar Interferometry) method using Sentinel-1 satellite data. The displacement anomalies are projected to the slanted satellite line-of-sight vector, and are given as a velocity anomaly (in units of meters/year), as this is the output of the applied DInSAR algorithm. Converting the observed line-of-sight anomaly, v LoS , to a vertical displacement, d vert , is then done ...
