2019-2020年全球海洋四维变分同化最优海气界面通量数据集

本数据是基于GECCO2全球海洋四维变分（伴随）数据同化和大洋状态估算系统（Köhl，2015；下称GECCO2K）更新后的配置而得出的2019年和2020年的各个变量，其中既包括海洋状态（温度、盐度、流速和海表高度），也包括优化后的海洋内部参数、海气界面参数，以及一些内部海洋通量，还包括初始海表面驱动场。本数据对GECCO2K的更新：在海洋过程中增加了各向异性涡致侧向混合系数Kapnu（Eden et al., 2007）;在控制变量中增加了各向异性涡致侧向混合系数Kapnu。

This dataset provides a suite of variables for the years 2019 and 2020, developed based on the updated configuration of the GECCO2 global ocean four-dimensional variational (adjoint) data assimilation and ocean state estimation system (Köhl, 2015; hereinafter referred to as GECCO2K).
It includes not only ocean states (temperature, salinity, ocean currents and sea surface height), but also optimized interior ocean parameters, air-sea interface parameters, selected internal ocean fluxes, as well as initial sea surface forcing fields.
The updates made to GECCO2K in this dataset are as follows: the anisotropic eddy-induced lateral mixing coefficient Kapnu (Eden et al., 2007) was added to the ocean processes, and the same anisotropic eddy-induced lateral mixing coefficient Kapnu was included in the control variables.
