IV. Results of Research
In this research, carbon-nitrogen coupled biogeochemical model as like CLM4 is used to couple GAIA earth system model for accurate predication for climate change and carbon cycle. In the evaluation of stranglement of ESM for simulating biogeochemical variables, the increasing gradient of amplitude of seasonal cycle of atmospheric CO₂ concentration with latitude is reasonably simulated in CESM-BGC including CLM4. However, amplitude of seasonal cycle is underestimated and 1 month early time lag is existed in the model. For improving carbon cycle between atmosphere and land in the model, the internal bias and external bias are needed to improve. The accurate anthropogenic emission data induces reduction of CO₂ bias in the model (external) in this study. Also, the uncertainty of nitrogen parameterization in the land affects the underestimation of GPP in high latitude over northern hemisphere (internal). These are caused by the biases of relationship between plants and important physical variables (temperature and precipitation) in the model. From this result, the development of carbon-nitrogen parameterization in the soil is need to improve simulation of biogeochemical processes in the model. The evaluation of mean climate and spatial distribution of GPP and NPP in GAIA-ESM with CLM4 shows reasonable results compared with observation and other CMIP5 ESMs. Moreover, GAIA-ESM has resonable results of oscillation of precipitation and GPP pattern by interannual variation as like ENSO. In the summary, GAIA ESM has good performances of simulating climate and carbon cycle compared with CMIP5 ESMs.
