Arctic Freeboard and Snow Depth From Near‐Coincident CryoSat‐2 and ICESat‐2 (CRYO2ICE) Observations: A First Examination of Winter Sea Ice During 2020–2022

Earth and Space Science
In the summer of 2020, ESA changed the orbit of CryoSat‐2 to align periodically with NASA's ICESat‐2 mission, a campaign known as CRYO2ICE, which allows for near‐coincident CryoSat‐2 and ICESat‐2 observations in space and time over the Arctic until ...

Detecting Sea Ice Leads and Floes in the Northwest Passage Using CryoSat-2

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
Knowledge 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 ...

Impact of CryoSat-2 for marine gravity field - globally and in the Arctic Ocean [PDF]

, 2012
CryoSat-2 offers at least four important improvements compared with conventional altimetry which should benefit marine gravity in general but particularly at high latitude.

Annual cycle in lakes and rivers from CryoSat-2 altimetry — The Brahmaputra river

, 2014
A key concern of the CryoSat-2 orbit has been its long repeat period of 369 days, which is usually undesirable for river and lake monitoring. However, the results of this study show that CryoSat-2 data can indeed be used for such monitoring by utilizing ...

High-Resolution Mass Trends of the Antarctic Ice Sheet through a Spectral Combination of Satellite Gravimetry and Radar Altimetry Observations

Remote Sensing, 2019
Time-variable gravity measurements from the Gravity Recovery and Climate Experiment (GRACE) and GRACE-Follow On (GRACE-FO) missions and satellite altimetry measurements from CryoSat-2 enable independent mass balance estimates of the Earth’s ...

CryoSat-2 Validation using CryoVEX 2011-12 Airborne Campaigns

, 2012
After the successful launch of CryoSat-2 in April 2010, ESA has funded two validation campaigns (CryoSat Validation Experiment, CryoVEx) of the satellite in the Arctic regions in the spring of 2011 and 2012. The primary aim of the CryoVEx campaigns is to

Optimising Interannual Sea Ice Thickness Variability Retrieved From CryoSat‐2

Geophysical Research Letters
Satellite radar altimeters like CryoSat‐2 estimate sea ice thickness by measuring the return‐time of transmitted radar pulses, reflected from the sea ice and ocean surface, to measure the radar freeboard.

Assimilating Summer Sea‐Ice Thickness Observations Improves Arctic Sea‐Ice Forecast

Geophysical Research Letters
Accurate 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.

Cryosat-2 Interferometric SAR Altimetry

, 2018
Cryosat-2 altimetry helps to assess the state of the Cryosphere by measuring elevation and elevation change. The SARIn mode of the Cryosat-2 SIRAL instrument is specifically designed for rough topography that we encounter near ice sheet margins.
