Greenland meltmaps 2007 - 2021
Parameters meltmap
Temporal Coverage 2007-01-01 to 2021-12-31
Release Date, Version 2023-08-30, 2.0
Producers / Owners ENVEO
Description The data set contains Greenland-wide daily melt extent/stage maps (presence of liquid water) from 2007 until 2021 derived from the ASCAT Enhanced Resolution Image Reconstruction (SIR) product. Additionally, based on the melt maps, the annual melt onset, end of the melt season and melt duration are also provided. Changes to version 01: Improved gap filling by considering the boundary values and categorizing them in the sequence of the melt cycle.

Greenland Ice Sheet velocity map from Sentinel-1, 2019/2020
Parameters iceVelocity
Temporal Coverage 2019-10-01 to 2020-09-30
Release Date, Version 2023-01-27, 1.3
Producers / Owners ENVEO
Description This dataset contains an annual ice velocity map of the Greenland Ice Sheet derived from Sentinel-1 data acquired from 2019-10-01 to 2020-09-30. The ice velocity is provided at 250 m grid spacing in North Polar Stereographic projection (EPSG: 3413). Provided is a NetCDF file with separate layers for the velocity components: vx, vy, vz, along with maps showing the magnitude of the horizontal components, the valid pixel count and uncertainty. This dataset was produced for the Copernicus Climate Change Service (C3S).

Ice Velocity of Icelandic Glaciers
Parameters iceVelocity
Temporal Coverage 2014-10-01 to 2020-12-31
Release Date, Version 2022-11-07, 1.0
Producers / Owners ENVEO
Description Ice velocity map of Icelandic glaciers derived from Sentinel-1 SAR data acquired from 2014-10-01 to 2020-12-31. The surface velocity is derived applying feature tracking techniques. The ice velocity map is provided at 100m 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), is derived from a digital elevation model. Provided is a NetCDF file with the velocity components: vx, vy, vz and vv (magnitude of the horizontal components), along with maps of valid pixel count and uncertainty (stdx, stdy). The product was generated by ENVEO.
