Version 2 of the EUMETSAT OSI SAF and ESA CCI sea-ice concentration climate data records
The Cryosphere, 2018 . We introduce the OSI-450, the SICCI-25km and the SICCI-50km climate data records of gridded global sea-ice concentration. These three records are derived from passive microwave satellite data and offer three distinct advantages compared to existing ...

Assimilation of sea-ice concentration in a global climate model — physical and statistical aspects [PDF]
, 2012 We investigate the initialisation of Northern Hemisphere sea ice in the global climate model ECHAM5/MPI-OM by assimilating sea-ice concentration data. The analysis updates for concentration are given by Newtonian relaxation, and we discuss different ways

Assimilation of sea surface temperature, sea ice concentration and sea ice drift in a model of the Southern Ocean [PDF]
Ocean Modelling, 2015 Current ocean models have relatively large errors and biases in the Southern Ocean. The aim of this study is to provide a reanalysis from 1985 to 2006 assimilating sea surface temperature, sea ice concentration and sea ice drift. In the following it is also shown how surface winds in the Southern Ocean can be improved using sea ice drift estimated from

Analysis of Sea Ice Timing and Navigability along the Arctic Northeast Passage from 2000 to 2019
Journal of Marine Science and Engineering, 2021 The ablation of Arctic sea ice makes seasonal navigation possible in the Arctic region, which accounted for the apparent influence of sea ice concentration in the navigation of the Arctic route.

Improved simulation of Antarctic sea ice due to the radiative effects of falling snow [PDF]
, 2017 Southern Ocean sea-ice cover exerts critical control on local albedo and Antarctic precipitation, but simulated Antarctic sea-ice concentration commonly disagrees with observations.

On the measure of sea ice area from sea ice concentration data sets
SPIE Proceedings, 2015 The measure of sea ice surface variability provides a fundamental information on the climatology of the Arctic region. Sea ice extension is conventionally measured by two parameters, i.e. Sea Ice Extent (SIE) and Sea Ice Area (SIA), both parameters being derived from Sea Ice Concentration (SIC) data sets.

Brief communication: impacts of ocean-wave-induced breakup of Antarctic sea ice via thermodynamics in a stand-alone version of the CICE sea-ice model [PDF]
, 2017 Impacts of wave-induced breakup of Antarctic sea ice on ice concentration and volume are investigated using a modified version of the CICE sea-ice model, run in standalone mode from 1979–2010.

Relationship between sea ice concentration and sea ice albedo over Antarctica
Korean Journal of Remote Sensing, 2015 Abstract : Sea ice is a key parameter for understanding the climate change in cryosphere. In this study,we investigated the correlation with the factors that influenced change of the sea ice extent. We used the SeaIce Concentration (SIC) from Ocean and Sea Ice Satellite Application Facility (OSI-SAF), and surface albedoprovided by The Satellite ...
