Description

The PROMICE Multi-year ice velocity product is an ice velocity mosaic consisting of several years of data for the Greenland Ice Sheet based on the ESA Sentinel-1 SAR offset tracking.
Currently, there are two mosaic in the product: one spanning 5 years of data from September 2016 to September 2021, and one spanning 7 years of data from January 2016 to December 2022.
The 5 year average product is a weighted average of all the Promice 24 day mosaics between September 2016 and September 2021 (Anne Solgaard; Anders Kusk, 2021, "Greenland Ice Velocity from Sentinel-1 Edition 2", https://doi.org/10.22008/promice/data/sentinel1icevelocity/greenlandicesheet, GEUS Dataverse, V27)
The 7 year average product is a weighted average of all the Promice 24 day mosaics between January 2016 and December 2022 (Solgaard, Anne Munck; Kusk, Anders, 2022, "Greenland Ice Velocity from Sentinel-1 Edition 3", https://doi.org/10.22008/FK2/ZEGVXU, GEUS Dataverse, V17)
Spatial resolution: 500 m
The mosaic is supplied as a NetCDF file. There is a high resolution png posted along with the NetCDF file.
