From: The effects of multiple environmental factors on global carbon allocation
Inter-annual variations in the global mean carbon allocation to the leaves (aleaf, a), wood (awood, b), and roots (aroot, c) of plants in the control simulation (right vertical axis and red line). Differences in the ratios of carbon allocation between the control simulation, and the fixed CO2 (CO2_fixed), fixed precipitation (Prec_fixed), fixed temperature (Tair_fixed), and fixed shortwave radiation (Swd_fixed) simulations (left vertical axis). For example, “aleaf_Control–aleaf_CO2_fixed” refers to the difference in values of aleaf between the control and the CO2_fixed simulations, while negative values mean that the changes in CO2 concentration led to decrease in aleaf.
