Figure 2: Posterior total fluxes versus CO2 vertical gradients and PBL concentrations for 2008–2010.
From: Top–down assessment of the Asian carbon budget since the mid 1990s
The annual mean flux (PgC per year) versus CO2 gradient (p.p.m.) between 1 and 4 km for each inversion is shown for East Asia (a), South Asia (b) and Southeast Asia (c). Also shown is the annual mean flux versus the PBL CO2 concentration (p.p.m.) for East Asia (d), South Asia (e) and Southeast Asia (f). Each of the inversions was sampled at the times and locations of the CONTRAIL aircraft data and the error bars show the 1-σ s.d. of the inversion results. The grey vertical lines indicate the values of the observed gradients and PBL concentrations and the shading shows the 1-σ s.d. The correlation (R2) between the fluxes and the gradients and PBL concentrations is given in each plot.
