A NEW WEATHER FILTER FOR REDUCING WEATHER EFFECT IN CALCULATING SEA ICE CONCENTRATION FROM AMSR2 DATA [PDF]
Ice concentration is one of the most fundamental parameters of sea ice which can be calculated from brightness temperatures measured by passive microwave radiometers such as AMSR2 onboard satellites.

Estimation of sea ice parameters from sea ice model with assimilated ice concentration and SST [PDF]
Abstract. A multi-category numerical sea ice model CICE along with data assimilation was used to derive sea ice parameters in the region of Baffin Bay and Labrador Sea. The assimilation of ice concentration was performed using the data derived from Advanced Microwave Scanning Radiometer (AMSR-E & AMSR2).

The 2018 North Greenland polynya observed by a newly introduced merged optical and passive microwave sea-ice concentration dataset [PDF]
Observations of sea-ice concentration are available from satellites year-round and almost weather-independently using passive microwave radiometers at resolutions down to 5 km.

Spatial-temporal variations of one-year ice in Antarctic different regions, 1988–2020
In order to increase the comparability of Antarctic sea ice changes, we proposed a new method to quantitatively assess the spatial–temporal variation characteristics of Antarctic one-year ice based on daily Antarctic sea ice concentration data provided ...

Convolutional neural networks (CNNs) are being increasingly investigated as a means to extract sea ice concentration from synthetic aperture radar (SAR) in an automated manner. This is often done using ice charts as training data.

Impurity Concentrations In Sea Ice [PDF]
AbstractThree different types of saline ice were cut into sections a few millimeters thick along planes parallel to the surface. The resulting melts were analyzed quantitatively for chloride, sulphate, sodium, potassium, magnesium, and calcium. Two of the specimens were artificial sea ice, grown in the laboratory at ambient temperatures of —30°C and ...

Consistent biases in Antarctic sea ice concentration simulated by climate models [PDF]
The simulation of Antarctic sea ice in global climate models often does not agree with observations. In this study, we examine the compactness of sea ice, as well as the regional distribution of sea ice concentration, in climate models from the latest

Relationship between sea ice concentration and sea ice albedo over Antarctica
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 ...

Relationships between Arctic sea ice drift and strength modelled by NEMO-LIM3.6 [PDF]
Sea ice cover and thickness have substantially decreased in the Arctic Ocean since the beginning of the satellite era. As a result, sea ice strength has been reduced, allowing more deformation and fracturing and leading to increased sea ice drift ...

Spatial Correlation Length Scales of Sea-Ice Concentration Errors for High-Concentration Pack Ice [PDF]
The European Organisation for the Exploitation of Meteorological Satellites-Ocean and Sea Ice Satellite Application Facility–European Space Agency-Climate Change Initiative (EUMETSAT-OSISAF–ESA-CCI) Level-4 sea-ice concentration (SIC) climate data records (CDRs), named SICCI-25km, SICCI-50km and OSI-450, provide gridded SIC error estimates in addition ...
