摘要：

The positive effect of rising atmospheric carbon dioxide concentration ([CO2]) on gross primary production (GPP) is one of the factors that determine the strength of the carbon sink provided by terrestrial ecosystems. CMIP5 models tended to underestimate this effect. The study of CMIP6 simulations of GPP shows that GPP sensitivity to [CO2] assumed by increasing CO2 seasonal-cycle amplitude falls within the range of the values assumed by model runs. This make it possible to find the weights that force the weighted mean of GPP simulations to satisfy the constraint imposed by increasing CO2 seasonal-cycle amplitude.
