Impacts of differing melt regimes on satellite radar waveforms and elevation retrievals

HIGHLIGHTS

• What: The authors investigate reliability of Offset Center Of Gravity (OCOG) and University College London Land-Ice (ULI) elevation retracking algorithms through analysis of_(and comparison with) level 1B waveform-derived leading-edge width (LeW). The authors generate a 2010 to 2021 LeW time series using temporal clustering and Bayesian model averaging and the authors compare them with level 2 OCOG and ULI elevation time series. Given the OCOG-derived elevations are ~ 1 m higher than in the ULI algorithm at NEEM and Summit (Figs 5a and 6a), the authors assess that the OCOG behaves as a . . .
