Arctic sea ice radar freeboard retrieval from the European Remote-Sensing Satellite (ERS-2) using altimetry: toward sea ice thickness observation from 1995 to 2021 [PDF]
The Cryosphere, 2023 Sea ice volume's significant interannual variability requires long-term series of observations to identify trends in its evolution. Despite improvements in sea ice thickness estimations from altimetry during the past few years thanks to CryoSat-2 and ...

Hydraulic Model Calibration Using CryoSat‐2 Observations in the Zambezi Catchment [PDF]
Water Resources Research, 2020 Abstract Geodetic altimeters provide unique observations of the river surface longitudinal profile due to their long repeat periods and densely spaced ground tracks. This information is valuable for calibrating hydraulic model parameters, and thus, for producing reliable simulations of water level for flood forecasting and river ...

CryoSat-2 waveform classification for melt event monitoring
Proceedings of the Northern Lights Deep Learning Workshop, 2022 Measuring the mass balance of ice sheets is important with respect to understanding among others sea level rise, glacier dynamics, global ocean circulation and marine ecosystems. One important parameter of the mass balance is surface melt, which can be estimated from different satellite data sources.

Mapping ice sheet grounding lines with CryoSat-2 [PDF]
Advances in Space Research, 2018 The boundary between grounded and floating ice is an important glaciological parameter, because it delineates the lateral extent of an ice sheet and it marks the optimal location for computing ice discharge. We present a method for detecting the grounding line as the break in ice sheet surface slope, computed from CryoSat-2 elevation measurements using

Classification of CryoSat-2 Radar Echoes [PDF]
, 2015 Sea-ice thickness at global scale is an important variable in the polar climate system. Only satellite altimeters such as onboard the CryoSat-2 mission allow us to obtain sea-ice thickness on hemispherical scale. Accurate CryoSat-2 altimeter range measurements provide surface elevations which have to be referenced to the local sea level to obtain sea ...

Retrieval of snow freeboard of Antarctic sea ice using waveform fitting of CryoSat-2 returns [PDF]
The Cryosphere, 2019 In this paper we develop a CryoSat-2 algorithm to retrieve the surface elevation of the air–snow interface over Antarctic sea ice. This algorithm utilizes a two-layer physical model that accounts for scattering from a snow layer atop sea ice as well as ...

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2022 CryoSat-2 repeatedly collects dense radar altimetry footprints covering high latitudes of the polar ice sheets for over ten years. The Baseline-D height product of CryoSat-2 was recently upgraded and released in 2019.
