Global surface ocean pCO2 from CSIR-ML6 (v2020)

An update to the original CSIR-ML6 method. The following changes have been made: SOCATv2020 is used; ERA5 wind data and MSLP are used (instead of ERA interim).<br><b>spco2</b> = surface pCO2 for the ensemble average<b>spco2_ensemble</b> = individual ensemble members of spco2<b>fgco2</b> = air-sea CO2 fluxes <b>area_mask</b> = the area per pixel - doubles as mask for the data<br>Please cite the dataset as well as the original publication (https://doi.org/10.5194/gmd-12-5113-2019).

本研究对原始CSIR-ML6方法进行了更新。本次更新作出如下调整：采用SOCATv2020数据集；使用ERA5风场数据与平均海平面气压（MSLP）替代ERA interim再分析数据。<br><b>spco2</b>：代表用于集合平均的表层二氧化碳分压（surface pCO2）<br><b>spco2_ensemble</b>：代表spco2的单个集合成员<br><b>fgco2</b>：代表海-气二氧化碳通量<br><b>area_mask</b>：表示单个像素对应的面积，同时兼作数据掩膜使用。<br>使用本数据集时，请一并引用本数据集及原始发表文献（https://doi.org/10.5194/gmd-12-5113-2019）。
