Version Summary
Version Summary
Changes for this version include:
- Addition of new parameter pt[x]/ref_surf/geoid_h, a weighted average of the geoid_h parameter from ATL06. This allows users to compare ATL11 height estimates to an approximation of local sea level.
- Addition of root attribute short_name.
- Modifications in quality assurance to allow for partial population of beam pair groups.
- Modification of ancilliary_data to correctly reflect ATL11 release and version numbers.
- Correction of /orbit_info/sc_orient_time as the dimension scale in that group.
- Addition of missing root level attributes.
- Modification of long_name of /pt[x]/crossing_track_data/h_corr to read ‘corrected height’.
- Bug fix that prevented the dynamic atmosphere correction from being calculated for along-track data.
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.
