This paper presents inverse modelling estimates of European methane (CH₄) emissions for 2006–2012 based on a new quality-controlled and harmonised in situ data set from 18 European atmospheric monitoring stations.

 Figure 3a. Annual total CH₄ emissions derived from inversions for northern, western, eastern, and southern Europe, and for EU-28 (coloured symbols; bars show estimated 2σ uncertainties). For comparison, anthropogenic CH4 emissions reported to UNFCCC (black line; grey range: 2σ uncertainty estimate based on National Inventory Reports), and from EDGARv4.2FT-InGOS (black stars) are shown. Furthermore, the blue lines show wetland CH₄ emissions from the WETCHIMP ensemble of seven models (mean, blue solid line; median, blue dashed line; minimum–maximum range, light-blue range). The previous estimates of total CH₄ emissions from Bergamaschi et al. (2015) for 2006 and 2007 are shown within the yellow rectangles.
