AMSR-E/AMSR2 Fram Strait Ice Speed

Data introduction

The Fram Strait is the main channel for the transport of Arctic sea ice to the North Atlantic, where sea ice accounts for 10% of the total Arctic sea ice. The existing satellite remote sensing ice speed data products have low time-space coverage, and the error of inversion of ice speed in the Fram Strait is too large. In response to these problems, the Polar Ocean Process and the Global Ocean Change Key Laboratory (POGOC) of the Ocean University of China and the Physical Ocean Key Laboratory of the Ministry of Education (POL) developed the Fram Strait area based on the AMSR-E/AMSR2 original orbital brightness temperature data. Sea Ice Motion (SIM). The ice speed inversion algorithm applies the Continuous Maximum Correlation Coefficient (CMCC) to the 89 GHz brightness temperature data, and improves the overlay encryption of the ice speed tracking template, effectively improving the ice speed inversion data. The spatial coverage and the accuracy of the data have also been improved.
