MEaSUREs Annual Greenland Outlet Glacier Terminus Positions from SAR Mosaics, Version 1 data set is now available at version 1.1. The minor changes in this version include:
- Added data for winters of 2014/2015, 2015/16, 2016/17
- Added new parameter attributes for the new data
- Added 29 new glaciers
- Provided a new GlacierID file with added glaciers and updated attributes
This data set is part of the Making Earth System Data Records for Use in Research Environments (MEaSUREs) Program.
NASA IceBridge-related CryoSat-2 Level 4 Sea Ice Elevation, Freeboard, and Thickness data are now published at the NASA National Snow and Ice Data Center Distributed Active Archive Center (NSIDC DAAC). This data set contains 30-day averaged Arctic sea ice thickness estimates, with freeboard and ice surface roughness, derived from from the ESA CryoSat-2 Synthetic Aperture Interferometric Radar Altimeter (SIRAL)
