A weekly Arctic sea-ice thickness data record from merged CryoSat-2 and SMOS satellite data [PDF]
The Cryosphere, 2017 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 ...

Impact of assimilating sea ice concentration, sea ice thickness and snow depth in a coupled ocean–sea ice modelling system [PDF]
The Cryosphere, 2019 The accuracy of the initial state is very important for the quality of a forecast, and data assimilation is crucial for obtaining the best-possible initial state.

Assessing the Impact of Lead and Floe Sampling on Arctic Sea Ice Thickness Estimates from Envisat and CryoSat‐2 [PDF]
Journal of Geophysical Research: Oceans, 2019 Multidecadal observations of sea ice thickness, in addition to those available for extent, are key to understanding long ‐ term variations and trends in the amount of Arctic sea ice. The European Space Agency's Envisat (2002 – 2010) and CryoSat ‐ 2 (2010

Retrieval and parameterisation of sea-ice bulk density from airborne multi-sensor measurements [PDF]
The Cryosphere, 2022 Knowledge of sea-ice thickness and volume depends on freeboard observations from satellite altimeters and in turn on information of snow mass and sea-ice density required for the freeboard-to-thickness conversion.
