Abstract

This dataset contains a time series of ice velocities for the Hagen Brae glacier in Greenland derived from Sentinel-1 SAR data acquired between 22/1/2015 and 1/6/2016. It has been produced by the ESA Greenland Ice Sheet Climate Change Initiative (CCI) project.

Data files are delivered in NetCDF format at 250m grid spacing in North Polar Stereographic projection (EPSG: 3413). The horizontal velocity components are provided in true meters per day, towards the EASTING(x) and NORTHING(y) directions of the grid.
