Carbon cycle modeling calculations for the IPCC.

摘要

We carried out essentially all the carbon cycle modeling calculations that were required by the IPCC Working Group 1. Specifically, IPCC required two types of calculations, namely, ''inverse calculations'' (input was CO(sub 2) concentrations and the output was CO(sub 2) emissions), and the ''forward calculations'' (input was CO(sub 2) emissions and output was CO(sub 2) concentrations). In particular, we have derived carbon dioxide concentrations and/or emissions for several scenarios using our coupled climate-carbon cycle modelling system.
