Retrieval of Snow Depth on Antarctic Sea Ice Using HY-2B Satellite Data
Sea ice and its surface snow depth are important factors of energy cycle and mass balance between atmosphere and ocean,and sensitive indicators of climate and environmen-tal change.This study attempts to apply Chinese HY-2B Sat-ellite Data to retrieve snow depth on Antarctic Sea ice.Re-sults show that the remote sensing retrieval model of Comio-so03 has the best accuracy with a spatial-temporal averaged deviation of-1.88 cm compared with that of Markus98 mod-el and Shen22 model against the snow measurements during the 35th Antarctic Scientific Expedition of China from the No-vember 2018 to January 2019.The HY-2B SMR snow depth on Antarctic sea ice is in good agreement with the GCOM-W1 AMSR-2 snow depth product(Comisto03 model).The difference between them mainly occurs in the sea ice ablation period and concentrate in the Antarctic Indian Ocean sector and the Western Pacific Ocean sector.Research on the re-mote sensing retrieval of snow depth on Antarctic Sea ice based on HY-2B SMR data could provide important data and technical support for the application of Chinese marine satel-lite series data to monitor long-term Antarctic Sea ice and snow changes.
