Comments :

Greenland Ice Sheet Velocity - Winter Campaigns of 2018/2019, 2019/2020 and 2020/2021: 100m gridded velocity map, generated from SAR interferometry applied SENTINEL-1 data acquired between 2018-12-01 and 2021-03-01.The velocity field is derived by combining INSAR results from overlapping ascending and descending orbits.

This data set is part of the ESA Greenland Ice sheet CCI project. The file is including all measurements and annotations.
It provides components of the ice velocity, along with maps showing the horizontal magnitude, valid pixel count and uncertainty (based on the std.) within a NetCDF file.
The ice velocity map is provided on a polar stereographic grid (EPSG 3413) with 100m grid spacing.
The horizontal velocity is provided in true meters per day, towards Easting (x) and Northing (y) direction of the grid. The vertical displacement is derived from a digital elevation model.
The product was generated by ENVEO.
