IAP全球海洋溶解氧格点数据集-1°产品

该数据集的原始数据为来自全球海洋数据库（WOD）中的CTD和 Bottle仪器，以及GDAC收集的Argo数据。IAP溶解氧格点数据应用了大气所提出的溶解氧偏差质控和偏差订正方案（Gouretski et al., 2023, under review)。同时，使用了大气所提出的插值方法（Mapping：改进的集合最优插值）对数据进行空间插值，该方法利用CMIP6多模式的历史模拟提供动力集合样本，以提供更好的背景误差协方差（Cheng & Zhu 2016）。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1958年至今（月平均）。数据获取地址：http://www.ocean.iap.ac.cn/ftp/cheng/IAP_v0_Ocean_Oxygen_gridded_1deg_0_6000m_dataset

The raw data of this dataset is sourced from CTD (Conductivity-Temperature-Depth) and Bottle instruments within the World Ocean Database (WOD), as well as Argo data collected by the Global Data Assembly Centre (GDAC). For the IAP dissolved oxygen gridded data, the dissolved oxygen bias quality control and bias correction scheme proposed by the Institute of Atmospheric Physics (IAP) (Gouretski et al., 2023, under review) was applied. Meanwhile, spatial interpolation was conducted using the interpolation method (Mapping: Improved Ensemble Optimal Interpolation) developed by the Institute of Atmospheric Physics. This method leverages historical simulation outputs from multiple CMIP6 (Coupled Model Intercomparison Project Phase 6) models to generate dynamic ensemble samples, thereby yielding more accurate background error covariance estimates (Cheng & Zhu 2016). This dataset has a horizontal resolution of 1°×1°, covers the water column from the surface down to 6000 meters with 119 vertical layers, and spans the period from 1958 to the present with monthly averaged data.
