TL;DR: In this paper, a revised version of the Simple Biosphere model (SiB2) is presented, incorporating a realistic canopy photosynthesis-conductance model to describe the simultaneous transfer of CO2 and water vapor into and out of the vegetation, respectively.

TL;DR: In this article, the exchange of carbon dioxide (CO 2 ) between the atmosphere and terrestrial ecosystems due to photosynthesis and respiration has been simulated using a new version of the simple biosphere model (SiB2) and the Colorado State University (CSU) general circulation model (GCM).

TL;DR: SiB2, the second-generation land-surface parameterization developed by Sellers et al., has been incorporated into the Colorado State University general circulation model and tested in multidecade simulation as discussed by the authors.

TL;DR: In this paper, an off-line version of a biosphere-atmosphere model, called SiB2, was used to simulate global land surface fluxes of energy and CO 2.

TL;DR: In this article, a new bulk transfer formulation for the surface turbulent fluxes of momentum, heat, and moisture has been developed by using the square root of the vertically averaged turbulent kinetic energy (TKE) in the atmospheric boundary layer as a velocity scale, in place of the mean wind speed.
