资源简介:
The CSIR-ML6-v2024 is an update to the original CSIR-ML6 method by Gregor et al. (2019), extending the CO2 data product until 2023-12-15. The following changes have been made:SOCAT-v2024 is used;ERA5 reanalysis wind data and mean sea level pressure (MSLP) are used (instead of ERA-interim);The gas-exchange coefficient (kw) used, is appropriately scaled for the ERA5 wind product as recommended by Fay and Gregor et al. (2021);fCO2, the sea surface fugacity of CO2 is reported as per the Global Carbon Budget recommendation instead of pCO2, the sea surface partial pressure of CO2.<br><b>NETCDF FILE:</b>The dataset is stored in a single netCDF file and it mainly contains the following data variables:sfco2 = surface fugacity of CO2 for the ensemble average (in µatm). Therefgco2 = air-sea CO2 fluxes (in mol m-2 yr-1)area = the ocean area per pixel (in m2) - doubles as mask for the data<br><b>CITATION</b>Please cite the dataset as Djeutchouang et al. (2024), see the DOI: 10.6084/m9.figshare.26564140, as well as the original publication by Gregor et al. (2019), see the DOI: 10.5194/gmd-12-5113-2019.<br><b>HOST</b>CSIR, Southern Ocean Carbon – Climate Observatory (SOCCO)
CSIR-ML6-v2024是Gregor等人(2019年)提出的原始CSIR-ML6方法的更新版本,将CO₂数据产品的时间范围扩展至2023-12-15。本次更新作出如下修改:
1. 采用SOCAT-v2024数据集;
2. 改用ERA5再分析风场数据与平均海平面气压(mean sea level pressure, MSLP),替代原有的ERA-interim数据;
3. 依据Fay与Gregor等人(2021年)的推荐,针对ERA5风场产品对气体交换系数(gas-exchange coefficient, k_w)进行了适配性缩放;
4. 按照《全球碳预算》(Global Carbon Budget)的规范,以海表面CO₂逸度分压(fCO₂)替代海表面CO₂分压(pCO₂)作为报告指标。
<b>NETCDF文件</b>:本数据集存储为单个netCDF格式文件,主要包含以下数据变量:
- sfco2:集合平均下的海表面CO₂逸度分压(单位:µatm);
- refgco2:海-气CO₂通量(单位:mol·m⁻²·yr⁻¹);
- area:各像素对应的海洋面积(单位:m²),同时可作为数据掩码使用。
<b>引用规范</b>:引用本数据集请标注Djeutchouang等人(2024年),对应DOI为:10.6084/m9.figshare.26564140;同时需引用Gregor等人(2019年)的原始研究,对应DOI为:10.5194/gmd-12-5113-2019。
