Greenland SENTINEL-1 ice velocity map from winter mapping campaign from 28 Dec 2017 to 28 Feb 2018.
Ice velocity map of Greenland derived from Sentinel-1 SAR data acquired from 2017-12-28 to 2018-02-28. In total approximately 1900 S-1A & S-1B scenes are used
to derive the surface velocity applying feature tracking techniques. The ice velocity map is provided at 500m grid spacing in North Polar Stereographic projection
(EPSG: 3413). The horizontal velocity is provided in true meters per day, towards EASTING(vx) and NORTHING(vy) direction of the grid, and the vertical displacement (vz),
derived from a digital elevation model (GIMP, Howatt et al. 2014), is also provided. Provided is a NetCDF file (including all measurements and annotation), with the
velocity components: vx, vy, vz and vv (magnitude of the horizontal components), along with maps showing valid pixel count and uncertainty (std.).
