CH4 top-down emissions from three high-latitude Arctic regions.

This dataset contains top-down emissions from three high-latitude Arctic regions (the North Slope of Alaska, the East Siberian Lowlands and the Taymyr Peninsula) using three different priors. Emissions were used in the publication "Ward et al., 2024 - Increasing methane emissions and widespread cold-season release from high-Arctic regions detected through atmospheric measurements" in review with JGR:Atmospheres. Top-down emissions were derived using the RHIME inverse model from the University of Bristol's Atmopsheric Chemistry Research Group. For more details on the model, inputs and region definitions please see the above publication.本数据集包含基于三种不同先验信息推导得到的北极高纬度三个区域（阿拉斯加北坡、东西伯利亚低地与泰梅尔半岛）的自上而下排放通量。该套排放数据已应用于Ward等人2024年的研究论文《通过大气观测检测到的高北极地区甲烷排放增长与广泛冷季释放》，此论文目前正在《JGR:Atmospheres》（《地球物理学研究杂志：大气》）接受同行评审。 本数据集的自上而下排放通量采用布里斯托大学大气化学研究组开发的RHIME反演模型（RHIME inverse model）推导得到。如需了解模型、输入数据及区域定义的更多细节，请参阅上述研究论文。
