1993-2021西北太平洋高分辨率温盐流数据产品

中科院海洋大科学研究中心共建单位海洋所张林林研究员、闫晓梅副研究员和孙澈研究员共同研制的西北太平洋高分辨率温盐流数据产品，是结合CTD、Argo等历史水文观测资料，以及最新的卫星高度计数据，利用基于海表面高度的地转经验模态方法（Height Geostrophic Empirical Mode, HGEM , Zhang & Sun, 2012）反演得到，即通过卫星高度计的大范围连续观测获取到的海洋三维温度、盐度和流速产品。

The high-resolution temperature-salinity-current dataset for the Northwest Pacific Ocean was jointly developed by Research Professors Zhang Linlin and Sun Che, and Associate Research Professor Yan Xiaomei from the Institute of Oceanology, Chinese Academy of Sciences (IOCAS), a co-construction unit of the CAS Ocean Science Research Center. This dataset was retrieved using the Height Geostrophic Empirical Mode (HGEM, Zhang & Sun, 2012) method based on sea surface height, incorporating historical hydrological observation data such as CTD and Argo, as well as state-of-the-art satellite altimetry data. It is a three-dimensional ocean product containing temperature, salinity and current velocity data obtained through large-scale continuous satellite altimeter observations.
