ESA Greenland Ice Sheet Climate Change Initiative (Greenland_Ice_Sheet_cci): Mass flow rate ice discharge (MFID) for Greenland from CCI IV, CCI SEC, and BedMachine v1.0
Abstract
Calving Front locations for Upernavik A,E,F, Humboldt and Hagen glaciers in Greenland, generated by deep learning based model using Sentinel-2 imagery.
The calving front location is generated by deep learning based model using Sentinel-2 imagery acquired from 2019-2020. The digitized calving fronts are stored in geosjons vector file format and include metadata information on the sensor and processing steps in the corresponding attribute table.
The 2022 CCI Calving Front Locations (CFL) release contains one primary dataset, the calving front locations, and auxuliary files to describe the file product: locations.png and glacier_locations.geojson for visualizing the glaciers, README and DESCRIPTION text files about the product structure, and a visual example how a calving front looks like. Greenland CCI Calving Front Locations (CFL) product is an experimental product using deep learning to automatically derive calving front locations for selected glaciers based on Sentinel-2 imagery at the end of the summer season.
The product was generated by S[&]T Norway.

| Data lineage: |
Ice discharge is calculated from the CCI Ice Velocity (IV) product, the CCI Surface Elevation Change (SEC) product (where it overlaps with the ice discharge gates), and ice thickness from BedMachine. Ice discharge gates are placed 10 km upstream from all marine terminating glacier termini that have baseline velocities of more than 150 m/yr. Results are summed by Zwally et al. (2012) sectors. The methods, including description of "coverage", are described in Mankoff et al. (2020; DOI: 10.5194/essd-12-1367-2020) |
