全球XBT温度廓线资料集（廓线）

XBT是抛弃式温深计，从1966年开始使用，是1966-2000期间最主要的海洋温度观测仪器，其观测存在系统性暖偏差。本数据集的xbt来源为WOD (World Ocean Database )，使用了一套完善的质量控制体系，CH14偏差订正方案。是一个国际XBT研究小组公认（推荐）的最优订正方案（由大气所联合NOAA和CSRIO的研究小组提出）。

XBT, short for Expendable Bathythermograph, has been in operational use since 1966 and was the primary ocean temperature observation instrument during the 1966 to 2000 period. Its observational data exhibit systematic warm biases. The XBT data in this dataset are sourced from the World Ocean Database (WOD), and a comprehensive quality control system as well as the CH14 bias correction scheme were adopted. The CH14 scheme, proposed by a research team jointly formed by the Institute of Atmospheric Physics, NOAA and CSRIO, is recognized and recommended as the optimal correction scheme by the international XBT research community.
