利用多种雷达测高数据制作每月5km北极海冰厚度产品(1995-2023)

北极海冰对区域和全球气候变化研究具有重要意义。卫星观测结果表明，北极海冰面积在过去 40 年中一直在下降。然而，由于卫星仪器无法直接测量北极海冰厚度（SIT），因此对其长期变化关注较少。在此，我们介绍了基于 ERS-2、Envisat 和 CryoSat-2 的多个雷达测高仪观测数据...

Arctic sea ice is of great significance for regional and global climate change research. Satellite observations show that the Arctic sea ice area has been declining over the past 40 years. However, due to the inability of satellite instruments to directly measure Arctic sea ice thickness (SIT), less attention has been paid to its long-term changes. Here, we present multiple radar altimeter observation data based on ERS-2, Envisat, and CryoSat-2...
