An improved CryoSat-2 sea ice freeboard retrieval algorithm through the use of waveform fitting

NT Kurtz, N Galin, M Studinger - The Cryosphere, 2014 - tc.copernicus.org
We develop a physical model capable of simulating the mean echo power of CryoSat-2 SAR-
and SARIn-mode waveforms over sea-ice-covered regions. The model simulations are used …

Retracking CryoSat-2, Envisat and Jason-1 radar altimetry waveforms for improved gravity field recovery

ES Garcia, DT Sandwell… - Geophysical Journal …, 2014 - academic.oup.com
Improving the accuracy of the marine gravity field requires both improved altimeter range
precision and dense track coverage. After a hiatus of more than 15 yr, a wealth of suitable …

A facet-based numerical model for simulating SAR altimeter echoes from heterogeneous sea ice surfaces

JC Landy, M Tsamados… - IEEE Transactions on …, 2019 - ieeexplore.ieee.org
Cryosat-2 has provided measurements of pan-Arctic sea ice thickness since 2010 with
unprecedented spatial coverage and frequency. However, it remains uncertain how the Ku …

Wind–wave interaction for strong winds

PAEM Janssen, JR Bidlot - Journal of Physical Oceanography, 2023 - journals.ametsoc.org
In this paper, we revisit the problem of wind–wave interaction with emphasis on strong
winds. For these events, it is assumed that nonlinearity is so large that the slope of the wind …

Using the interferometric capabilities of the ESA CryoSat-2 mission to improve the accuracy of sea ice freeboard retrievals

TWK Armitage, MWJ Davidson - IEEE Transactions on …, 2013 - ieeexplore.ieee.org
A significant source of error in the retrieval of sea ice freeboard from pulse-limited radar
altimeters arises when scattering from off-nadir leads dominates the power echo causing the …

Improved retrieval of land ice topography from CryoSat-2 data and its impact for volume-change estimation of the Greenland Ice Sheet

J Nilsson, A Gardner, L Sandberg Sørensen… - The …, 2016 - tc.copernicus.org
