We present results from simulations with noresm2 that were carried out for the sixth phase of the coupled model intercomparison project (cmip6). Dramatic improvements in vegetation biogeography result when clm3.5 is coupled to a dynamic global vegetation model We assess an ensemble of simulations, including prescribed and prognostic vegetation state, multiple forcing data sets, and clm4, clm4.5, and clm5, against a range of metrics including from the international land model benchmarking (ilambv2) package. The model has been used in both the 5th and the 6th phases of cmip (cmip5, cmip6), and for evaluation of the difference between a 1.5 and 2 deg Noresm is based on the community earth system model cesm (danabasoglu et al., 2020). To improve our understanding of the controls over the fertilization responses of the new model, we assess sensitivity to eight parameters pertinent to the cycling of carbon and nitrogen by vegetation, both under present‐day conditions and with co2 and nitrogen fertilization.
The community land model (clm) is the land component of the community earth system model (cesm) and is used in several global and regional modeling systems In this paper, we introduce model developments included in clm version 5 (clm5), which is the default land component for cesm2. Parametric and structural updates in community land model version 5 (clm5) improve its ability in capturing terrestrial biogeochemical dynamics
