Variability of Arctic sea ice thickness and volume from CryoSat-2 [PDF]
Philosophical Transactions of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2015 We present our estimates of the thickness and volume of the Arctic Ocean ice cover from CryoSat-2 data acquired between October 2010 and May 2014. Average ice thickness and draft differences are within 0.16 m of measurements from other sources (moorings, submarine, electromagnetic sensors, IceBridge).

Remote Sensing, 2021 This paper estimates lake level variations over two small and adjacent lakes in the Tibetan plateau (TP), namely Gemang Co and Zhangnai Co, as well as the inland Dianchi Lake in China using CryoSat-2 SARIn-mode and LRM 20-Hz waveforms over the period of ...

A high resolution record of Greenland mass balance [PDF]
We map recent Greenland Ice Sheet elevation change at high spatial (5-km) and temporal (monthly) resolution using CryoSat-2 altimetry. After correcting for the impact of changing snowpack properties associated with unprecedented surface melting in 2012 ...

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.

Impact assessment of snow thickness, sea ice density and water density in CryoSat-2-derived sea ice thickness [PDF]
The CryosphereSea ice thickness is an essential climate variable, which is often derived from satellite altimetry freeboard estimates, e.g., by CryoSat-2. In order to convert freeboard to sea ice thickness, assumptions are needed for snow thickness, snow density, sea ...

Arctic lead detection using a waveform mixture algorithm from CryoSat-2 data [PDF]
We propose a waveform mixture algorithm to detect leads from CryoSat-2 data, which is novel and different from the existing threshold-based lead detection methods.

A weekly Arctic sea-ice thickness data record from merged CryoSat-2 and SMOS satellite data [PDF]
Sea-ice thickness on a global scale is derived from different satellite sensors using independent retrieval methods. Due to the sensor and orbit characteristics, such satellite retrievals differ in spatial and temporal resolution as well as in the ...

Greenland Ice Sheet Elevation Change From CryoSat‐2 and ICESat‐2
Geophysical Research LettersAlthough fluctuations in ice sheet surface mass balance lead to seasonal and interannual elevation changes, it is unclear if they are resolved differently by radar and laser satellite altimeters.

Snow depth estimation on leadless landfast ice using Cryo2Ice satellite observations [PDF]
The CryosphereObservations of snow on Arctic Sea ice are vitally important for sea ice thickness estimation, bio-physical processes, and human activities. While previous studies have combined CryoSat-2- and ICESat-2-derived freeboards to estimate snow depth over ...
