Assessing CryoSat‐2 Antarctic Snow Freeboard Retrievals Using Data From ICESat‐2
Earth and Space Science, 2021 NASA's Ice, Cloud, and land Elevation Satellite‐2 (ICESat‐2) laser altimeter launched in Fall 2018, providing an invaluable addition to the polar altimetry record generated by ESA's CryoSat‐2 radar altimeter.

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 ...

Evaluation and Validation of CryoSat-2-Derived Water Levels Using In Situ Lake Data from China
Remote Sensing, 2019 CryoSat-2 altimetry has become a valuable tool for monitoring the water level of lakes. In this study, a concentrated probability density function (PDF) method was proposed for preprocessing CryoSat-2 Geophysical Data Record (GDR) data.

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.

Monitoring Arctic thin ice: a comparison between CryoSat-2 SAR altimetry data and MODIS thermal-infrared imagery [PDF]
The Cryosphere, 2023 Areas of thin sea ice in the polar regions not only are experiencing the highest rate of sea-ice production but also are, therefore, important hot spots for ocean ventilation as well as heat and moisture exchange between the ocean and the atmosphere ...

CRUCIAL: Cryosat-2 Success over Inland Water and Land [PDF]
, 2014 CRUCIAL is an ESA/STSE funded project investigating innovative land and inland water applications from Cryosat-2 with a forward-look component to the future Sentinel-3 mission. The fact that the Earth’s land surface is, in general, a relatively poor reflector of Ku band energy, with the exceptions of inland water, salar and ice surfaces has enabled ...

Joint inversion estimate of regional glacial isostatic adjustment in Antarctica considering a lateral varying Earth structure (ESA STSE Project REGINA) [PDF]
, 2017 A major uncertainty in determining the mass balance of the Antarctic ice sheet from measurements of satellite gravimetry, and to a lesser extent satellite altimetry, is the poorly known correction for the ongoing deformation of the solid Earth caused by

Antarctic Grounding Line Mapping From CryoSat‐2 Radar Altimetry [PDF]
Geophysical Research Letters, 2017 AbstractWe present a new technique for mapping the grounding line of Antarctic ice shelves using a combination of CryoSat‐2 standard and swath elevation data. Our method is based on detecting the tidal signal in pseudo crossovers and is tested on the Siple Coast region of West Antarctica.
