摘要：
The radar altimeter onboard China's HY-2B satellite was launched in October 2018. In this paper, we processed the HY-2B L1 altimetry data from October 2020 to April 2021. The radar freeboard was preliminarily estimated from the HY-2B altimetry data over the Arctic sea ice. We validated the HY-2B radar freeboard estimates using the radar freeboard products from the Alfred Wegener Institute (AWI). The overall difference between the HY-2B radar freeboard estimates and the AWI data is 0.088 +/- 0.057 m.
