Dataset
EOCIS: Ice Sheet Velocity, V1
Abstract
This dataset contains Ice Sheet Velocity data produced within the Earth Observation Climate Information Service (EOCIS) project by the Satellite Ice Dynamics Group at the University of Leeds. The Antarctic Ice Sheet Ice Velocity product provides annual means of ice speed (ice velocity magnitude) at 250 m resolution for the Antarctic Ice Sheet from 2015 to 2024. This dataset contains the key variables ice speed (annual mean of ice velocity magnitude for the Antarctic Ice Sheet), and ice speed uncertainty (mean uncertainty corresponding to the ice speed measurement).
These data are derived from ESA Sentinel-1 SAR Interferometric Wide (IW) mode data and match the spatial footprint of this source. These data cover the margin of the Antarctic Ice Sheet, including ice shelves, north of approximately 78°S.

Process overview
| Title | EOCIS Ice Sheet Velocity, V1 |
| Abstract | These annual mosaics of ice velocity are generated from Sentinel-1 synthetic aperture radar (SAR) interferometric wide (IW) mode data. Measurements which are input these annual mosaics were generated using the intensity feature tracking method implemented with the GAMMA Remote Sensing software package. Georeferencing was completed within this processing chain using the NSIDC 1km Antarctic DEM (https://doi.org/10.5067/H0FQ1KL9NEKM) and the Reference Elevation Model of Antarctica version 1 (https://doi.org/10.5194/tc-13-665-2019). Annual mosaics are the mean of all available tracking results.
