Assessment of Lead Discrimination from CryoSat-2 [PDF]

, 2012
Sea ice is strongly affecting the global climate, and the sea ice extent has been monitored by satellites since 1979. To estimate the Arctic sea ice volume, ice thickness must be determined. The measurements of sea ice thickness are however more difficult to achieve, and encounter limitations due to spatial and temporal variability. The measurements of

Satellite altimetry detection of ice-shelf-influenced fast ice [PDF]

The Cryosphere, 2021
The outflow of supercooled Ice Shelf Water from the conjoined Ross and McMurdo ice shelf cavity augments fast ice thickness and forms a thick sub-ice platelet layer in McMurdo Sound.

Возможности исследования возрастных характеристик льда Карского моря на основе спутниковых данных СryoSat-2 и SMOS [PDF]

, 2023
Sea ice age is a proxy for thickness, which can be obtained through the use of satellite data. The paper presents the results of comparison of CryoSat-2, SMOS and CryoSat-2 & SMOS fusion data with detailed ice charts (October–April, 2010–2018).

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 ...

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 ...

CryoSat-2 waveform classification for melt event monitoring

Proceedings of the Northern Lights Deep Learning Workshop, 2022
Measuring the mass balance of ice sheets is important with respect to understanding among others sea level rise, glacier dynamics, global ocean circulation and marine ecosystems. One important parameter of the mass balance is surface melt, which can be estimated from different satellite data sources.

Mean sea surface and mean dynamic topography determination from Cryosat-2 data around Australia

, 2021
In this study, we use seven years of Cryosat-2 data to improve Mean Sea Surface (MSS) and also to estimate Mean Dynamic Topography (MDT) around Australia.

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 ...

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 ...
