Description

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.

Version Description

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
