World Ocean Atlas of Argo inferred statistics

this dataset provides a world ocean atlas of argo inferred statistics. the primary data are exclusively argo profiles. the statistics are done using the whole time range covered by the argo data, starting in july 1997. the atlas is provided with a 0.25° resolution in the horizontal and 63 depths from 0 m to 2,000 m in the vertical. the statistics include means of conservative temperature (ct), absolute salinity, compensated density, compressiblity factor and vertical isopycnal displacement (vid); standard deviations of ct, vid and the squared brunt vaisala frequency; skewness and kurtosis of vid; and eddy available potential energy (eape). the compensated density is the product of the in-situ density times the compressibility factor. it generalizes the virtual density used in roullet et al. (2014). the compressibility factor is defined so as to remove the dependency with pressure of the in-situ density. the compensated density is used in the computation of the vid and the eape.

本数据集提供了基于 Argo 推断的世界海洋大图统计数据。主要数据为 Argo 剖面数据。统计范围涵盖 Argo 数据的整个时间序列，始于 1997 年 7 月。该图集以 0.25° 的分辨率提供水平数据，并在垂直方向上提供从 0 米至 2,000 米的 63 个深度层。统计数据包括保守温度（CT）、绝对盐度、补偿密度、压缩因子以及垂直等密度面位移（VID）；CT、VID 以及平方布伦特-瓦伊萨拉频率的标准差；VID 的偏度和峰度；以及涡旋可用势能（EAPE）。补偿密度是现场密度与压缩因子的乘积。它是对 Roullet 等人（2014）中使用的虚拟密度的推广。压缩因子被定义为消除现场密度与压力的依赖性。补偿密度用于 VID 和 EAPE 的计算。
