IAP全球海洋热含量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）中的所有现场温度观测数据，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度，垂向覆盖从表层到6000米，包括0-100米、0-300米、0-700米、0-1500米、0-2000米、0-3000米、0-4000米、0-5000米、0-6000米热含量。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/

The raw data of this dataset consists of all in-situ temperature observation records from the World Ocean Database (WOD), collected using various instruments including XBT, CTD, Argo, Bottle, MBT, Glider, mooring, etc. Additionally, some proprietary data was incorporated into the dataset. State-of-the-art bias correction methods for XBT/MBT/Bottle/APB data were employed; a novel data quality control system (CODC-QC) was adopted; and updated climatological means were utilized. Meanwhile, the interpolation method proposed by the Institute of Atmospheric Physics, namely "Mapping: Dynamic Sample-based Ensemble Optimal Interpolation", was applied for spatial interpolation of the dataset. The dataset has a horizontal resolution of 1°, with vertical coverage spanning from the surface down to 6000 meters, including heat content estimates in layers of 0-100 m, 0-300 m, 0-700 m, 0-1500 m, 0-2000 m, 0-3000 m, 0-4000 m, 0-5000 m and 0-6000 m. The temporal coverage ranges from 1940 to the present, with monthly averaged data. Data access URL: http://www.ocean.iap.ac.cn/ftp/cheng/IAPv4_IAP_Temperature_gridded_1month_netcdf/
