ATLAS/ICESat-2 L3B Slope-Corrected Land Ice Height Time Series, Version 5 (ATL11)
Data set:
ATL11
This is the most recent version of these data.
Version Summary
Changes for this version include:

  • Added cycles 12, 13, 14, and 15 of the ICESat-2 data.

  • Removed orbit specific parameters from /orbit_info group as crossing time, rgt, orbit_number, and sc_orient are not needed for ATL11.

  • Implemented mean-tide inclusion for converting geoid heights.

Overview

This data set provides time series of land-ice surface heights derived from the ICESat-2 ATL06 Land Ice Height product. It is intended primarily as an input for higher level gridded products, but can also be used on its own as a spatially organized product that allows easy access to height-change information derived from ICESat-2 observations.
