Towards Improved Mapping of Sea Ice Concentration and Sea Ice Thickness with SWOT

Observing sea ice concentration (SIC) and thickness (SIT) remains a key challenge for climate monitoring and modeling. Satellite altimetry provides measurements of ice and sea level anomaly from which can be estimated SIC, sea ice freeboard, and ultimately SIT.

Response of passive microwave sea ice concentration algorithms to thin ice

2014 IEEE Geoscience and Remote Sensing Symposium, 2014
The 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.

Validation of SSM/I sea ice concentration algorithms for the Okhotsk Sea

IGARSS '98. Sensing and Managing the Environment. 1998 IEEE International Geoscience and Remote Sensing. Symposium Proceedings. (Cat. No.98CH36174), 1998
Satellite passive microwave radiometers, such as SSM/I, can observe sea ice distribution at global scale. Two sea ice concentration algorithms, namely the NASA Team algorithm and the Bootstrap algorithm were compared for the Okhotsk Sea. Though the correlation coefficient of the two ice concentrations were 0.97, the Bootstrap ice concentrations were ...

Enhanced Arctic Ice Concentration Estimation Merging MODIS Ice Surface Temperature and SSM/I Sea-Ice Concentration

Atmosphere-Ocean, 2014
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, 1995
This 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.

Advancing the understanding of cyclone impacts on Arctic sea-ice concentration and sea-ice lead formation

Cyclones are an important driver of heat and moisture transport into the Arctic and additionally cause high wind speeds and abrupt wind direction changes during their passage. The subsequent impacts on the Arctic sea ice cover consist of i) a thermodynamic stalling/enhancement of the seasonal sea-ice growth/melt, and ii) enhanced drift and deformation ...
