Comparison of observation- and inventory- based CH4 emissions for eight large global emitters

CoCO2 (https://coco2-project.eu/) is a scientific collaborative effort funded by the H2020 European Commissions, grant number 958927. This synthesis has been originally based on data and country specific plots from previous VERIFY project, for the EU27: https://webportals.ipsl.fr/VERIFY/FactSheets, v1.28 and on the WP8 deliverable Reports D8.1 (https://coco2-project.eu/node/333), D8.2 (https://coco2-project.eu/node/360) and D8.3 (https://coco2-project.eu/index.php/node/406) from the CoCO2 project website. This dataset is updated after we received two review comments. Each spreadsheet contains the CH4 data behind the manuscript figures, both as time series, mean values and uncertainties (min, max ranges). Units are mentioned for each figure. For the gridded figures data should be asked directly from the data providers.CoCO2（https://coco2-project.eu/）是一项由欧盟委员会地平线2020（H2020）计划资助的科学合作项目，资助编号为958927。 本综合数据集最初基于针对欧盟27国的VERIFY项目的相关数据与国别专属图表（版本v1.28，来源链接：https://webportals.ipsl.fr/VERIFY/FactSheets），以及CoCO2项目官网发布的第8工作包（WP8）交付报告D8.1（https://coco2-project.eu/node/333）、D8.2（https://coco2-project.eu/node/360）与D8.3（https://coco2-project.eu/index.php/node/406）。 本数据集在收到两条评审意见后完成更新。每份电子表格均包含支撑该论文插图的甲烷（CH4）数据，涵盖时间序列、平均值及不确定度（最小值、最大值区间）三类形式。每幅插图均标注了对应数据的单位。若需获取网格化插图所用数据，请直接向数据提供方申请。
