Data Set ID: 

ATLAS/ICESat-2 L3B Annual Land Ice Height, Version 4

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.

There is a more recent version of these data.

Version Summary: 

Changes for this version include:

  • Added cyces 10 and 11 of the ICESat-2 data.
  • The group attribute poly_exponent_list has been removed from ATL11. The same information is available from the /ptx/ref_surf/poly_exponent_x and /ptx/ref_surf/poly_exponent_y datasets.
