Atmospheric observations consistent with reported decline in the UK's methane emissions (2013-2020)
Atmospheric measurements can be used as a tool to evaluate national greenhouse gas inventories through inverse modelling. Using 8 years of continuous methane (CH4) concentration data, this work assesses the United Kingdom's (UK) CH4 emissions over the period 2013-2020. Using two different inversion methods, we find mean emissions of 2.10±0.09 and 2.12±0.26Tgyr-1 between 2013 and 2020, an overall t
