Improving Multiyear Sea Ice Concentration Estimates with Sea Ice Drift [PDF]
Remote Sensing, 2016 Multiyear ice (MYI) concentration can be retrieved from passive or active microwave remote sensing observations. One of the algorithms that combines both observations is the Environmental Canada Ice Concentration Extractor (ECICE).

On the assimilation of ice velocity and concentration data into large-scale sea ice models [PDF]
Ocean Science, 2007 Data assimilation into sea ice models designed for climate studies has started about 15 years ago. In most of the studies conducted so far, it is assumed that the improvement brought by the assimilation is straightforward.

The impact of melt ponds on summertime microwave brightness temperatures and sea-ice concentrations [PDF]
The Cryosphere, 2016 Sea-ice concentrations derived from satellite microwave brightness temperatures are less accurate during summer. In the Arctic Ocean the lack of accuracy is primarily caused by melt ponds, but also by changes in the properties of snow and the sea-ice ...

Vertical ocean heat redistribution sustaining sea-ice concentration trends in the Ross Sea. [PDF]
Nat Commun, 2017 AbstractSeveral processes have been hypothesized to explain the slight overall expansion of Antarctic sea ice over the satellite observation era, including externally forced changes in local winds or in the Southern Ocean’s hydrological cycle, as well as internal climate variability.

DETAILED VALIDATION OF AMSR2 SEA ICE CONCENTRATION DATA USING MODIS DATA IN THE SEA OF OKHOTSK [PDF]
ISPRS Annals of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2020 Global warming is one of the most serious problems we are facing in the 21st Century. Sea ice has an important role of reflecting the solar radiation back into space.

Multi-year spatial distribution of Antarctic sea ice (1988 - 2017)
Terrestrial, Atmospheric and Oceanic Sciences, 2021 In this study, we used daily sea-ice concentration data from the National Snow and Ice Data Center from 1988 to 2017 to investigate the spatial distribution of Antarctic sea ice by calculating the annual mean sea-ice concentration and multi-year sea ice ...

New methodology to estimate Arctic sea ice concentration from SMOS combining brightness temperature differences in a maximum-likelihood estimator [PDF]
The Cryosphere, 2017 Monitoring sea ice concentration is required for operational and climate studies in the Arctic Sea. Technologies used so far for estimating sea ice concentration have some limitations, for instance the impact of the atmosphere, the physical ...
