IV map of Greenland from Sentinel-1 SAR data acquired from 2015-10-01 to 2016-10-31.
Ice velocity map of Greenland derived from Sentinel-1 SAR data acquired from 2015-10-01 to 2016-10-31. 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.).
