(a) Detrended and smoothened CH4 surface emissions estimates from TM5-4DVAR for the same regions as in Fig. 1. The variability of GFED4s biomass burning emissions has been subtracted. (b) δ13C-CH4 measurements54 corrected for the influence of transport using a meteorology-only TM5 simulation of δ13C-CH432. The light shaded regions represent the ±1σ uncertainty of the respective time series.
