Summary
Abstract: GLAH05 Level-1B waveform parameterization data include output parameters from the waveform characterization procedure and other parameters required to calculate surface slope and relief characteristics. GLAH05 contains parameterizations of both the transmitted and received pulses and other characteristics from which elevation and footprint-scale roughness and slope are calculated. The received pulse characterization uses two implementations of the retracking algorithms: one tuned for ice sheets, called the standard parameterization, used to calculate surface elevation for ice sheets, oceans, and sea ice; and another for land (the alternative parameterization). Each data granule has an associated browse product.

Quality Each data granule has associated browse products that users can quickly view to determine the general quality of the data in the granule. Altimeter Frame Quality Flag is included in file level global attributes and includes a corrections flag. Indicates if all data in frame are good with appropriate corrections applied; or if some of data are not corrected or have measurement problems.
