Sea Ice Thickness and Coverage

Based on GNSS reflectometry remote sensing technology, this product retrieves the spatiotemporal distribution of global sea ice thickness and coverage by analyzing ice surface reflectivity characteristics and reflected power spectrum information. It enables all-weather, all-time monitoring of sea ice conditions in polar and high-latitude regions, providing fundamental data support for characterizing sea ice structural features and evolutionary trends.

A Key Data Capability for Polar Environmental Change Monitoring

Sea ice thickness and coverage are critical physical parameters reflecting polar climate change and air–sea interactions. They directly influence the Earth's energy balance, ocean circulation patterns, and the stability of the global climate system. High-precision, continuous sea ice observation data help reveal seasonal variability and long-term evolutionary trends, strongly supporting climate change assessment, polar environmental prediction, and the optimization of global climate models.

Sea Ice Thickness and Coverage

Application

Climate Change Monitoring and Assessment

Through long-term accumulation of thickness and coverage data, analyze interannual and decadal variations in polar sea ice to provide scientific evidence for climate change assessment and policy formulation.

Numerical Climate and Ocean Model Assimilation

Assimilate sea ice thickness and coverage data into climate and ocean dynamic models to improve prediction accuracy and model stability in polar regions.

Polar Navigation Safety Support

Provide real-time sea ice thickness and distribution information for Arctic route planning and vessel operations, reducing navigation risks and optimizing route selection.

Marine Resource Development

Support environmental risk assessment and engineering design optimization for polar oil and gas exploration, marine infrastructure construction, and resource survey activities.
