Atmospheric Ocean System
The Atmospheric Ocean System comprises the Upwelling-Diffusion Climate Model, the Oceanic Carbon Model and
Geographical Pattern Scaling.
Oceanic Carbon Model, documentation, input and outputDocumentationThe Oceanic Carbon Model (OCM) of IMAGE 2.4, which is identical to the one in IMAGE 2.2, simulates the carbon (C) flux between the atmosphere and ocean with the Bern Carbon Cycle model (Bern-CC) as described by Joos et al. (1996). This model is a box-diffusion type oceanic carbon model. The model is based on a mixed-layer-pulse-response function, which allows for describing time-dependent non-linear effects of seawater chemistry resulting from changes in the atmospheric CO2 concentration. This non-linearity occurs in the chemical equilibria involving the buffering system formed by undissociated CO2 and HCO3 and CO32 ions. The analytical representation of the mixed layer response function of the Princeton 3-D model (Joos et al., 1996) is used In IMAGE. | Model input and output | | Model input |
