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

Monthly glacier mass changes from CryoSat-2 radar altimetry
, 2023 We generate a record of ice loss across glaciers globally for the first time from CryoSat-2 swath interferometric radar altimetry. CryoSat-2’s orbital sub-cycle of 30 days allows us to resolve changes at high temporal resolution for Alaska, Arctic Canada

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

Remote 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.

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

Antarctic ice shelf thickness from CryoSat‐2 radar altimetry [PDF]
Geophysical Research Letters, 2015 AbstractIce shelf thickness for the whole of Antarctica is derived from 4 years (2011–2014) of CryoSat‐2 (CS2) radar altimetry measurements using the assumption that the shelves are in hydrostatic equilibrium. The satellite orbit and novel synthetic aperture radar interferometric mode of CS2 results in 92.3% data coverage over the ice shelves, with ...

Using microwave imager observations to improve the ocean temperature in a coupled NWP system
Quarterly Journal of the Royal Meteorological Society, EarlyView.A recent upgrade to the ECMWF IFS has implemented outer‐loop coupling between the atmosphere and the ocean. This work uses this method to pass ocean skin temperature estimates derived from satellite‐borne microwave imagers to the ocean data assimilation system; the updated ocean state is then passed back to the atmospheric system.
