Optimising assimilation of sea ice concentration in an Earth system model with a multicategory sea ice model [PDF]
Tellus A: Dynamic Meteorology and Oceanography, 2018 A data assimilation method capable of constraining the sea ice of an Earth system model in a dynamically consistent manner has the potential to enhance the accuracy of climate reconstructions and predictions. Finding such a method is challenging because the sea ice dynamics is highly non-linear, and sea ice variables are strongly non-Gaussian ...

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 ...

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.

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 ...
