Extended Data Fig. 2: Monthly subcontinental Chinese CO2 flux estimates.
From: Large Chinese land carbon sink estimated from atmospheric carbon dioxide data
a, Map showing the subcontinental geographical regions over China where we report a posteriori CO2 fluxes. Colours denote the proportion of each region that falls within mainland China. b–i, Monthly regional a priori and a posteriori biosphere CO2 fluxes (Pg C month−1) over China during 2010–2016. A posteriori fluxes are inferred from data used in the SR-1 and SR-2 inversions (see main text). Vertical bars and the orange envelope denote a priori and a posteriori uncertainties. NWC, northwest China; NC, northern China; NE, northeast China; TP, Tibetan Plateau; CC, central China; EC, eastern China; SW, southwest China; SE, southeast China, as shown in a.
