Introduction One figure is described below that uses Taylor diagrams (described in the text) to evaluate how well the MATCH simulation reproduces observed interannual variability in atmospheric CO2 at a range of monitoring stations. In contrast to Figure 6, the supplemental figure shows results when MATCH is forced with the original CASA/GFED v.2 CO2 fluxes, without optimizing the biomass burning component based on the CO inversion. 1. 2007jg000408-fs01.eps Figure S1. Taylor diagrams comparing IAV in model total and component CO2 tracer growth rate to GLOBALVIEW observations. Symbols are as described in Figure 2. (a) Total CO2, best case except using uncorrected biomass burning fluxes. (b) Uncorrected biomass burning component of GFED.
