IAP全球海洋温度1°格点数据集第四版 (更新至IAPv4.2)

该数据集的原始数据为来自全球海洋数据库（WOD）中的所有现场观测数据，包括XBT, CTD, Argo, Bottle, MBT, Glider, mooring等观测仪器；此外还添加了一些自有的数据。使用了最新的XBT/MBT/Bottle/APB数据偏差订正方法；使用了新的数据质量控制系统（CODC-QC）；使用了新的气候平均态；同时，使用了大气所提出的插值方法（Mapping：基于动态样本的集合最优插值）对数据进行空间插值。数据集水平分辨率为1°×1°，垂向覆盖从表层到6000米（119层），时间范围从1940年至今（月平均）。数据获取地址：http://www.ocean.iap.ac.cn/ftp/cheng/IAPv4_IAP_Temperature_gridded_1month_netcdf/

This dataset is developed using all in-situ observational data from the World Ocean Database (WOD), including observations from instruments such as XBT, CTD, Argo, Bottle, MBT, Glider and mooring. Additionally, some in-house collected observational data are incorporated. State-of-the-art bias correction methods for XBT, MBT, Bottle and APB datasets have been applied. A novel data quality control system (CODC-QC) has been utilized. A new climatological mean dataset has been employed. Furthermore, a spatial interpolation method proposed by the Institute of Atmospheric Physics (Mapping: Dynamic Sample-based Ensemble Optimal Interpolation) has been used to perform spatial interpolation on the dataset. The resulting dataset has a horizontal resolution of 1° × 1°, covers the water column from the sea surface down to 6000 meters with 119 vertical layers, spans the time period from 1940 to the present, and provides monthly averaged products.
