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 ...

The performance and potentials of the CryoSat-2 SAR and SARIn modes for lake level estimation [PDF]
, 2017 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 ...

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 ...

Response of Pacific-sector Antarctic ice shelves to the El Niño/Southern Oscillation. [PDF]
, 2018 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.

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.

Validation of CryoSat-2 SARIn Data over Austfonna Ice Cap Using Airborne Laser Scanner Measurements
Remote Sensing, 2018 The study presented here is focused on the assessment of surface elevations derived from CryoSat-2 SARIn level 1b data over the Austfonna ice cap, Svalbard, in 2016.

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 ...

A new Arctic MSS model derived from combined Cryosat-2 and ICESat observations
International Journal of Digital Earth, 2022 Due to the existence of seasonal or perennial sea ice cover, the determination of the Arctic sea surface is more difficult than that of mid-low latitudinal oceans.

Wet tropospheric correction for satellite altimetry using SIRGAS-CON products
Journal of Geodetic Science, 2022 The wet tropospheric correction (WTC) is a required correction to satellite altimetry measurements, mainly due to the atmospheric water vapor delay. On-board microwave radiometers (MWR) provide information for WTC estimation but fail in coastal zones and
