Sea Ice Concentration from the RADARSAT Constellation Mission for Numerical Sea Ice Prediction
2021 IEEE 19th International Symposium on Antenna Technology and Applied Electromagnetics (ANTEM), 2021In this study, our technique for automated extraction of sea ice concentration from RADARSAT-2 data was adapted to the recently launched RADARSAT Constellation mission (RCM). Ice concentrations were derived from more than 2,600 RCM images acquired between August 1, 2020 and March 31, 2021.

Abstract The current GFDL seasonal prediction system, the Seamless System for Prediction and Earth System Research (SPEAR), has shown skillful prediction of Arctic sea ice extent with atmosphere and ocean constrained by observations. In this study we present improvements in subseasonal and seasonal predictions of Arctic sea ice by directly assimilating

Sea ice concentration and motion assimilation in a sea ice−ocean model
Journal of Geophysical Research: Oceans, 2008A sea ice concentration and motion assimilation scheme has been developed using the Met Office Forecasting Ocean Assimilation Model (FOAM). FOAM has been upgraded to include a more realistic sea ice rheology and a sea ice thickness distribution. The sea ice data assimilation scheme uses Special Sensor Microwave Imager (SSMI) and QuikSCAT satellite ...

The deuterium concentration in Arctic sea ice
Journal of Geophysical Research, 1961Samples taken from cores of sea ice collected near Ice Island T-3 at 80°18′N, 113°W, and on US-IGY Drifting Station Alpha at approximate locations of 85°40′N, 127°W, and 83°N, 165°W, were analyzed for their relatives deuterium content. A plot of deuterium concentration vs.

Oscillatory behavior in Arctic sea ice concentrations
Journal of Geophysical Research: Oceans, 1996We have done a frequency analysis of the 9‐year record of sea ice concentrations obtained with the NASA Nimbus 7 scanning multichannel microwave radiometer (SMMR). Because of the periodic revisit time of the SMMR, we are able to examine recurrence of shorter‐period oscillations, as aliased by the revisit frequency, and longer‐period oscillations per se.

This paper assessed the accuracy of four passive microwave (PM) sea ice concentration (SIC) products in polar regions by using twelve scenes MODIS images under clear-sky conditions. The SIC products include the DMSP SSMIS with Arctic Radiation and Turbulence Interaction Study Sea Ice (ASI) algorithm (SSMIS/ASI), the GCOM-W AMSR2 with NASA Bootstrap (BT)

AbstractIce concentration data from passive microwave sensors are not reliable during the summer melt season. In this study passive microwave ice concentration estimates are improved upon through the assimilation of ice surface temperature data from the Moderate-Resolution Imaging Spectroradiometer (MODIS).

Monthly average polar sea-ice concentration
Data Series, 1995This data set represents the results of calculations carried out on sea-ice-concentration data from the SMMR and SSM/I instruments. The original data were obtained from the National Snow and Ice Data Center (NSIDC). The data set also contains the source code of the programs that made the calculations.

Response of passive microwave sea ice concentration algorithms to thin ice
2014 IEEE Geoscience and Remote Sensing Symposium, 2014The influence of sea ice thickness brightness temperatures and ice concentrations retrieved from passive microwave observations is quantified, using horizontally homogeneous sea ice thickness retrievals from ESA's SMOS sensor observations at high incidence angles.

Temporal mixture analysis of SMMR sea ice concentrations
IGARSS '96. 1996 International Geoscience and Remote Sensing Symposium, 2002Introduces the idea of temporal mixture analysis (TMA) for analyzing long sequences of hypertemporal remote sensing imagery. The basis of this approach is spectral mixture analysis, which the authors adapt from the spectral domain to the time domain and apply it to a 9-year record of sea ice concentrations in the Northern Hemisphere.
