Detection and Characterization of Ship Targets Using CryoSat-2 Altimeter Waveforms [PDF]

open access: yesRemote Sensing, 2016
This article describes an investigation of the new possibilities offered by SAR altimetry compared with conventional altimetry in the detection and characterization of non-ocean targets. We explore the capabilities of the first SAR altimeter installed on the European Space Agency satellite CryoSat-2 for the detection and characterization of ships.

Comparison of Arctic Sea Ice Thickness from Satellites, Aircraft, and PIOMAS Data

open access: yesRemote Sensing, 2016
In this study, six Arctic sea ice thickness products are compared: the AVHRR Polar Pathfinder-extended (APP-x), ICESat, CryoSat-2, SMOS, NASA IceBridge aircraft flights, and the Pan-Arctic Ice Ocean Modeling and Assimilation System (PIOMAS).

The performance and potentials of the CryoSat-2 SAR and SARIn modes for lake level estimation [PDF]

open access: yes
Over the last few decades, satellite altimetry has proven to be valuable for monitoring lake levels. With the new generation of altimetry missions, CryoSat-2 and Sentinel-3, which operate in Synthetic Aperture Radar (SAR) and SAR Interferometric (SARIn ...

Calibrating the SAR SSH of Sentinel-3A and CryoSat-2 over the Corsica Facilities

open access: yesRemote Sensing, 2018
Initially developed to monitor the performance of TOPEX/Poseidon and to follow the Jason legacy satellite altimeters at Senetosa Cape, Corsica, this calibration/validation site has been extended to include a new location at Ajaccio. This addition enables

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

open access: yesThe Cryosphere, 2014
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 to show the importance of variations in the radar backscatter coefficient with ...

CryoSat-2 Significant Wave Height in Polar Oceans Derived Using a Semi-Analytical Model of Synthetic Aperture Radar 2011–2019

open access: yesRemote Sensing, 2021
This paper documents the retrieval of significant ocean surface wave heights in the Arctic Ocean from CryoSat-2 data. We use a semi-analytical model for an idealised synthetic aperture satellite radar or pulse-limited radar altimeter echo power.

Response of Pacific-sector Antarctic ice shelves to the El Niño/Southern Oscillation. [PDF]

open access: yes
Satellite observations over the past two decades have revealed increasing loss of grounded ice in West Antarctica, associated with floating ice shelves that have been thinning.

A Spatiotemporal Comparison and Assessment of Multisource Satellite Derived Sea Ice Thickness in the Arctic Thinner Ice Region

open access: yesIEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
The accuracy and reliability of the latest version of multisource satellite derived Arctic sea ice thickness (SIT) in thinner ice regions are currently uncertain.

Antarctic grounding zone characteristics from CryoSat-2 [PDF]

open access: yes, 2019
Abstract. We present the results of mapping the limit of tidal flexure (point F) and hydrostatic equilibrium (point H) of the grounding zone of Antarctic ice shelves from CryoSat-2 standard and swath elevation data. Overall we were able to map 41 % of the grounding zone of the larger floating ice shelves and outlet glaciers in Antarctica.

Applications for CryoSat-2 satellite magnetic data in studies of Earth’s core field variations

open access: yesEarth, Planets and Space, 2021
We use 20 years of continuous magnetic field measurements from the Ørsted, CHAMP and Swarm satellite missions, supplemented by calibrated platform magnetometer data from the CryoSat-2 satellite, to study time variations of the Earth’s core field at ...
