Fig. 2From: Implications of overestimated anthropogenic CO2 emissions on East Asian and global land CO2 flux inversion a Comparisons of CH4 inversion results (black: a priori; blue: a posteriori) for the East Asia (EA) region with the EDGAR42FT estimated anthropogenic emissions for China. The linear fits to the annual mean values are shown as lines, with slopes the fits marked. b Linear relationship of anthropogenic CO2 and CH4 emissions for China over the period of 1970–2012 (Olivier et al. 2014). The inter-decadal values are marked by text and red circles Back to article page
