Supporting Data - Sentinel-1 Detection of Ice Slabs on the Greenland Ice Sheet

This dataset contains supporting data accompanying Culberg, R., Michaelides, R. J., and Miller, J. Z.: Sentinel-1 Detection of Ice Slabs on the Greenland Ice Sheet, EGUsphere [preprint], https://doi.org/10.5194/egusphere-2023-2652, 2023. The final accepted manuscript will be linked via the same preprint server at the time of publication. The dataset contains the following files:

• Sentinel-1 HV and HV/HH backscatter mosaics of the Greenland Ice Sheet formed using data from 1 Oct 2016 - 30 April 2017.
• Estimated average annual summer melt extent between 1 Nov 2014 and 31 Aug 2020, detected using seasonal variations in Sentinel-1 HH backscatter.
• The firn aquifer extent over Greenland derived from Sentinel-1 in Brangers et al. (2020), reprojected to EPSG:3413.
• The ice mask used in the study, derived from the BedMachine Greenland ice mask.
• The training and validation datasets derived from the Jullien et al. (2023) ice slabs detections from ice penetrating radar data that were used to optimize ice slab detection thresholds for the Sentinel-1 backscatter mosaics.
