Process Based Surface Modeling

Parallel to the advancement of the top-down approach has been the development of "bottom-up," spatially explicit, process-based models for the ocean initiated by Maier-Reimer and Hasselmann (1987) (see also Greenblatt and Sarmiento, Chapter 13, this volume, for a summary of the state of the art up to now) and the terrestrial biosphere initiated by Esser (1987) (see also McGuire et al. 2001 for a summary of the state of the art up to now). These models simulate the spatial and temporal evolution of sources and sinks as driven by the key natural and anthropogenic drivers of the carbon cycle: atmospheric CO2 concentration, observed variations of climate (temperature, precipitation, surface winds, radiation, buoyancy fluxes, etc.), and historical patterns of land use. The most comprehensive, global simulation experiments to date have been undertaken through the Ocean Carbon Model Intercomparison Project (OCMIP; Orr et al. 2001), and the Carbon Cycle Model Linkage Project (CCMLP; McGuire et al. 2001).
