第四版大气物理研究所（IAPv4）海洋温度和海洋热含量（OHC）客观分析产品主要考虑了质量控制（QC）程序、气候学、偏差校正、垂直和水平插值以及制图等方面的最新发展，并提供了自 1940 年（1957 年以后更可靠）以来 6000 米以上（119 层）的月度数据，数据集的水平分辨率为 1°×1°，垂直覆盖范围从地表到 6000 米（119 层），时间范围从 1940 年至今（月平均）。", "ds_source": "
IAPv4 温度网格产品的数据源来自世界海洋数据库 (WOD)，包括所有可用的观测数据，包括来自 XBT、CTD、Argo、Bottle、MBT、Glider、系泊和其他仪器的现场数据，以及一些中国数据。

IAPv4 was compared with the previous version IAPv3, as well as other data products, sea surface temperature (SST), and satellite observation data. Compared with IAPv3, the long-term increase of 2000 meter OHC in the upper layer of IAPv4 from 1955 to 2023 is slightly stronger, mainly due to the newly developed deviation correction. During the period of 2005-2023, the trend of 0-2000 meter OHC in IAPv4 was also higher than that in IAPv3, mainly due to updates in the quality control process. The top layer of IAPv4 is consistent with the independent SST dataset. Compared with IAPv3 and other OHC products investigated in this study, IAPv4 has a smaller monthly OHC variability, and the trend of ocean warming rate (i.e. warming acceleration) is more consistent with the net energy imbalance at the top of the atmosphere than IAPv3. The sea level budget can be closed within an uncertain range.", "ds_ref_way": "", "ds_abstract": "
The fourth edition of the Institute of Atmospheric Physics (IAPv4) objective analysis product for ocean temperature and ocean heat content (OHC) mainly considers the latest developments in quality control (QC) procedures, climatology, deviation correction, vertical and horizontal interpolation, and mapping, and provides monthly data of over 6000 meters (119 layers) since 1940 (more reliable since 1957). The horizontal resolution of the dataset is 1 °× 1 °, and the vertical coverage range is from the surface to 6000 meters (119 layers), with a time range from 1940 to the present (monthly average).
