Roll Calibration for CryoSat-2: A Comprehensive Approach [PDF]
Remote Sensing, 2021 CryoSat-2 is the first satellite mission carrying a high pulse repetition frequency radar altimeter with interferometric capability on board. Across track interferometry allows the angle to the point of closest approach to be determined by combining ...

Polar Ocean Tides—Revisited Using Cryosat-2 [PDF]
Remote Sensing, 2023 With the availability of more than 9 years of Cryosat-2, it is possible to revisit polar ocean tides, which have traditionally been difficult to determine from satellite altimetry.

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.

Lead and Floe Detection From CryoSat‐2 Radar and ICESat‐2 Laser Altimetry
Earth and Space ScienceDifferences in satellite sampling affect their ability to resolve small‐scale features over Arctic sea ice. For CryoSat‐2 (CS2) and ICESat‐2 (IS2) these differences are driven by geometric (footprint resolution) and radiometric (radar or laser) sampling.

Optimising Interannual Sea Ice Thickness Variability Retrieved From CryoSat‐2
Geophysical Research LettersSatellite radar altimeters like CryoSat‐2 estimate sea ice thickness by measuring the return‐time of transmitted radar pulses, reflected from the sea ice and ocean surface, to measure the radar freeboard.

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 ...

Synthesis of the ICESat/ICESat-2 and CryoSat-2 observations to reconstruct time series of lake level
International Journal of Digital Earth, 2023 Synthesis of multi-satellite altimetry facilitates the acquisition of long-term changes in lake level but may induce biases due to inconsistent data sources, and thus remains largely unexplored.

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 ...
