The MEaSUREs Greenland Quarterly Ice Sheet Velocity Mosaics from SAR and Landsat, Version 5 and MEaSUREs Greenland Monthly Ice Sheet Velocity Mosaics from SAR and Landsat, Version 5 datasets are now available. These datasets can be accessed through the NASA National Snow and Ice Data Center Distributed Active Archive Center (NSIDC DAAC). The quarterly and monthly datasets have been recalibrated using an improved balance velocity estimate and excluding 2000-m GPS points from the 1990s. A correction has been made for the submergence/emergence velocity using an average of Racmo and MAR SMB for the period from 1958 to 2021, and for the solid Earth tides using PySolid (https://github.com/insarlab/PySolid).
In addition, new data have been added, and the quarterly and monthly datasets now span from 01 December 2014 to 30 November 2022. The “LS8” in the filenames of the Landsat-specific files has been replaced by “LS” as these products now include Landsat 9 in addition to Landsat 8 from 2022 onwards. These datasets are part of the NASA Making Earth System Data Records for Use in Research Environments (MEaSUREs) program.
