Abstract

This dataset contains a time series of ice velocities for the Helheim Glacier in Greenland derived from Sentinel-1 SAR data acquired between between 17/1/2015 and 11/6/2016. 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.
