Greenland ice velocity map 2016/2017 from Sentinel-1
Parameters iceVelocity
Temporal Coverage 2016-12-23 to 2017-02-27
Release Date, Version 2017-03-20, 1.0
Producers / Owners ENVEO
Description Ice velocity map of Greenland derived from Sentinel-1 SAR data acquired from 2016-12-23 to 2017-02-27. In total approximately 1800 S-1A & S-1B scenes are used to derive the surface velocity applying feature tracking techniques. The ice velocity map is provided at 250 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, is also provided. Provided are both a single NetCDF file (including all measurements and annotation), and separate GeoTiff files with the velocity components: vx, vy, vz and vv (magnitude of the horizontal components), along with maps showing valid pixel count and uncertainty (std.).

Parameters calvingFront
Temporal Coverage 1990-01-01 to 2016-12-31
Release Date, Version 2017-03-17, 3.0

Description Calving Fronts from 28 Glaciers in Greenland, derived with manual delineation from geocoded ERS, LANDSAT 5,7,8 and Copernicus Sentinel-1 data



Ice velocity Larsen B Glaciers, Antarctic Peninsula, 2009-2011
Parameters iceVelocity
Temporal Coverage 2009-09-29 to 2011-02-17
Release Date, Version 2017-02-08, 1.0
Producers / Owners ENVEO
Description Ice velocity of Larsen B Glaciers and SCAR Inlet, Antarctic Peninsula, from ALOS PALSAR data acquired in 2009 and 2011. The dataformat is 3-layer GeoTiff: the first two layers represent the horizontal displacement component easting and northing respectively in output map coordinates and converted to meters per day [m/d]. The third layer represents the vertical velocity and is derived from the height difference along the displacement vector taken from a DEM.



Ice velocity Larsen B Iceshelf, Antarctic Peninsula, 1995
Parameters iceVelocity
Temporal Coverage 1995-11-07 to 1996-03-24
Release Date, Version 2017-02-08, 2.0
Producers / Owners ENVEO
Description This data set provides a surface velocity dataset of the Larsen-B Ice Shelf (Antarctic Peninsula) with a grid size of 50m. The surface velocity field was derived by combining ascending and descending ERS-1 and ERS-2 interferometric pairs. The velocity field is a compilation of ERS-1 and ERS-2 data acquired between Oct 1995 & March 1996. The dataformat is 2-layer GeoTiff representing the horizontal displacement component easting and northing respectively in output map coordinates and converted to meters per day [m/d].

Release Date, Version 2016-09-30, 1.0
Producers / Owners ENVEO
Description Ice velocity map of Greenland from Copernicus Sentinel-1 SAR data. The dataformat is 3-layer GeoTiff: the first two layers represent the horizontal displacement component easting and northing respectively in output map coordinates and converted to meters per day [m/d]. The third layer represents the vertical velocity and is derived from the height difference along the displacement vector taken from a DEM. Also included is a 1-layer geocoded GeoTiff representing magnitude of velocity in meters per day [m/d]
