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

On sea ice concentration anomaly coherence in the southern Beaufort Sea [PDF]
Geophysical Research Letters, 2005 The circumpolar flaw lead polynya system is a region of enhanced biological productivity and for significant portions of the annual cycle, dominates the exchange of energy and mass across the ocean‐sea ice‐atmosphere (OSA) interface. We investigate the nature of sea ice concentration (SIC) anomalies for spatial and temporal statistical persistence ...

Sea ice inertial oscillations in the Arctic Basin [PDF]
, 2012 International audienceAn original method to quantify the amplitude of inertial motion of oceanic and ice drifters, through the introduction of a non-dimensional parameter M defined from a spectral analysis, is presented.

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2022 Sea ice concentration algorithms using brightness temperatures ($T_{B}$) from satellite microwave radiometers are used to compute sea ice concentration ($c_{\text{ice}}$), sea ice extent, and generate sea ice climate data records. Therefore, it is important to minimize the sensitivity of $c_{\text{ice}}$ estimates to geophysical noise caused by snow ...

The Arctic sea ice cover of 2016: a year of record-low highs and higher-than-expected lows [PDF]
The Cryosphere, 2018 The Arctic sea ice cover of 2016 was highly noteworthy, as it featured record low monthly sea ice extents at the start of the year but a summer (September) extent that was higher than expected by most seasonal forecasts.

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.

Remote Sensing, 2018 Warming of the Arctic leads to a decrease in sea ice, and the decrease of sea ice, in turn, results in warming of the Arctic again. Several microwave sensors have provided continuously updated sea ice data for over 30 years.

Super Resolution of Arctic Sea Ice Concentration
, 2021 Arctic sea ice concentration is often coarsely observed and numerically computed despite its importance for polar climate system. In this work we present three machine-learning methods to recover the original high-resolution images from the coarse-grained low-resolution counterparts.

Remote Sensing, 2014 Extensive sea ice over Arctic regions is largely involved in heat, moisture, and momentum exchanges between the atmosphere and ocean. Some previous studies have been conducted to develop statistical models for the status of Arctic sea ice and showed ...
