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.
