Description

This data set (ATL10) contains estimates of sea ice freeboard, calculated using three different approaches. Sea ice leads used to establish the reference sea surface and descriptive statistics used in the height estimates are also provided. The data were acquired by the Advanced Topographic Laser Altimeter System (ATLAS) instrument on board the Ice, Cloud and land Elevation Satellite-2 (ICESat-2) observatory.

Version Description

Changes for Version 6 include:
  • Added AMSR2 sea ice concentration (SIC) data, which provides a higher resolution grid than the existing SIC file
  • Removed interpolated reference surfaces with no sea ice segments
  • Updated the mean sea surface (MSS) variables description
  • Updated the ATL10 group structure
  • Implemented land filtering
