Antarctic Grounding Line Location from Sentinel-1A/B double-difference interferometry, 2019, supporting "Antarctic ice-shelf advance driven by anomalous atmospheric and sea-ice circulation".

This dataset contains ESRI shapefiles of Larsen C Ice Shelf’s grounding line location (GLL), 2019, as constrained from double-difference interferometric synthetic aperture radar (SAR) techniques applied to ESA Sentinel-1a/b SAR imagery. Multiple GLLs are provided and correspond to the position of the grounding line as imaged from consecutive Sentinel-1a/b 6-day repeat-pass interferometric image pairs acquired during austral winter and early springtime (June, July, August, and September) of 2019. Further methods are outlined in the associated manuscript, and detailed information on the metadata associated with each shapefile is provided in the README.txt file.
