XBT and CTD pairs dataset Version 1

The XBT/CTD pairs dataset (Version 1) is the dataset used to calculate the historical XBT fall rate and temperature corrections presented in Cowley, R., Wijffels, S., Cheng, L., Boyer, T., and Kizu, S. (2013). Biases in Expendable Bathythermograph Data: A New View Based on Historical Side-by-Side Comparisons. Journal of Atmospheric and Oceanic Technology, 30, 1195–1225, doi:10.1175/JTECH-D-12-00127.1.

4,115 pairs from 114 datasets were used to derive the fall rate and temperature corrections. Each dataset contains the scientifically quality controlled version and (where available) the originator's data. The XBT/CTD pairs are identified in the document 'XBT_CTDpairs_metadata_V1.csv'.
Note that future versions of the XBT/CTD pairs database may supersede this version. Please check more recent versions for updates to individual datasets.

XBT/CTD配对数据集（版本1）是用于计算Cowley等人2013年发表的研究中提及的历史投弃式温深仪（Expendable Bathythermograph, XBT）与温盐深仪（Conductivity-Temperature-Depth, CTD）沉降速率及温度校正参数的数据集。相关研究文献为：Cowley R, Wijffels S, Cheng L, Boyer T, Kizu S. 2013. 投弃式温深仪数据偏差：基于历史同步对比的新视角. 《大气和海洋技术杂志》，30卷，1195–1225页，DOI:10.1175/JTECH-D-12-00127.1。

本研究从114个数据集中共提取4115组配对数据，用于推导沉降速率与温度校正参数。每份数据集均包含经过科学质量管控的版本，以及（若有提供的）原始创建者观测数据。XBT/CTD配对数据的相关元数据可在文档"XBT_CTDpairs_metadata_V1.csv"中查询。

请注意，XBT/CTD配对数据库的后续版本可能会取代本版本。若需获取各数据集的更新内容，请查阅最新版本。
