We thank the Japanese Aerospace Exploration Agency, National Institute for Environmental Studies, and the Ministry of Environment for the GOSAT data and their continued support as part of the Joint Research Agreement. We thank Anthony Bloom for supplying wetland CH4 emissions. This research used the ALICE High Performance Computing Facility at U. Leicester and the Arc1 facility at U. Leeds. TCCON data were obtained from the TCCON Data Archive, hosted by the Carbon Dioxide Information Analysis Center (CDIAC) (tccon.onrl.gov). NOAA atmospheric CH4 dry air mole fractions were obtained from the NOAA ESRL GMD Carbon Cycle Cooperative Global Air Sampling Network (esrl.noaa.gov).
