ATLAS/ICESat-2 L3B Slope-Corrected Land Ice Height Time Series, Version 6
Data set id:
DOI: 10.5067/ATLAS/ATL11.006
This is the most recent version of these data.
Version Summary
Changes for Version 6 are as follows:

-Corrected height bias from geolocation imperfections
-Adjusted y polynomial fit sensitivity for small distances
-Added dh_geoloc to /ptx/crossing_track_data
-Added dh_geoloc to /ptx/cycle_stats
-Removed slope_change_t0, slope_change_rate_x, slope_change_rate_x_sigma, slope_change_rate_y, and slope_change_rate_y_sigma from /ptx/ref_surf


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.
