Sudden mega natural gas leaks of two Nord Stream pipelines in the Baltic Sea (Denmark) occurred from late September to early October 2022, releasing large amounts of methane into the atmosphere. We inferred the methane emissions of this event based on surface in situ observations using two inversion methods and two meteorological reanalysis datasets, supplemented with satellite-based observations. We conclude that approximately 220 ± 30 Gg of methane was released from September 26 to October 1, 2022.
2022年9月下旬至10月初，波罗的海（丹麦海域）的两条北溪天然气管道突然发生大规模天然气泄漏，向大气中释放了大量甲烷。我们利用两种反演方法和两个气象再分析数据集，基于地面原位观测，并辅以卫星观测，推断了该事件的甲烷排放量。我们得出结论，2022年9月26日至10月1日期间，大约释放了220±30Gg的甲烷。
