This version improved TOF, range calibrations, and range bias correction (average change in range is ~ -0.7 mm); Added a variable (max_valid_stren_strong) to the first photon bias and radiometric correction tables to reflect invalid correction values due to unreliable calibration values; Changed to ITRF2020, resulting in a 7 mm regional height change with maximum values at poles; ANC03/04 products generated from POD solutions use updated global modeling; Correction to the center-of-mass data set generation in ANC04, which should shift the z-component by ~1.0–1.2 cm during airplane mode periods; ANC05 products were calibrated using results from recent full mission week calibration solutions; Used GEOS5-IT for atmosphere delay calculation from NASA GMAO; Updated tide model to an extrapolated FES2014b for ocean, load and long-period tides; Parameters affected in /gtx/geophys_corr include tide_ocean, tide_load, and tide_equilibrium; Updated weight_ph to use DDA-03’s Radial Basis Function Normalized for Instrument Characteristics; Added signal_class_ph as experimental DDA-03 parameter to classify photons using algorithms developed for evaluating weight_ph; Updated quality_ph to include flag values to identify noise bursts and streaks, and all photons in a pulse that are considered nearly or fully saturated and whether the return occurs at the surface, after pulse, impulse response; Added beta_angle and orbit_angle at geoseg rate, carried forward from ATL03g; Cloud optimization of H5 files for more efficient access/use in cloud environments.
