Lake Level Estimation Based on CryoSat-2 SAR Altimetry and Multi-Looked Waveform Classification
Remote Sensing, 2016 In this study, reliable water levels for four lakes are estimated based on an innovative processing strategy using a semi-automatic CryoSat-2 Synthetic Aperture Radar (SAR) multi-looked waveform classification.

Comparison between gravity gradients from dense CryoSat-2 altimetry and from shipborne gradiometry [PDF]
, 2017 Satellite altimetry is a tool to gather information about Earth’s oceans and ice coverage on a global extent. Altimetric data can be used to monitor ice sheet changes, create bathymetric maps or analyze the sea surface.

Detecting Sea Ice Leads and Floes in the Northwest Passage Using CryoSat-2
IEEE Journal of Selected Topics in Applied Earth Observations and Remote SensingKnowledge of sea ice lead and floe density is important for ship navigation, understanding ice pack dynamics, and mapping primary productivity. Furthermore, reliable lead and floe discrimination is essential for the calculation of sea ice freeboard and ...

Constraining the mass balance of East Antarctica [PDF]
, 2017 We investigate the mass balance of East Antarctica for the period 2003-2013 using a Bayesian statistical framework. We combine satellite altimetry, gravimetry, and GPS with prior assumptions characterizing the underlying geophysical processes.

Uncertainties in Arctic sea ice thickness and volume: new estimates and implications for trends [PDF]
, 2013 Sea ice volume has decreased in the last decades, evoked by changes in sea ice area and thickness. Estimates of sea ice area and thickness rely on a number of geophysical parameters which introduce large uncertainties.

New insight from CryoSat-2 sea ice thickness for sea ice modelling [PDF]
, 2019 Estimates of Arctic sea ice thickness are available from the CryoSat-2 (CS2) radar altimetry mission during ice growth seasons since 2010. We derive the sub-grid scale ice thickness distribution (ITD) with respect to 5 ice thickness categories used in a ...

Water level analysis in Tibet using CryoSat-2
, 2019 While the water level monitoring inTibet suffers data gaps due to insufficient in situ gauge stations, the satellite altimetry serves as an efficient alternative. In this work, measurements from the CryoSat-2 mission are employed and analyzed to determine water level time series in various lakes throughout Tibetan region. The time series are calculated

Assimilating Summer Sea‐Ice Thickness Observations Improves Arctic Sea‐Ice Forecast
Geophysical Research LettersAccurate Arctic sea‐ice forecasting for the melt season is still a major challenge because of the lack of reliable pan‐Arctic summer sea‐ice thickness (SIT) data.
