Process oriented models with descriptions of biogeochemical processes in terrestrial ecosystem have normally a focus on some components and on some time scale related to the use of the model. The CoupModel will have an emphasize on the interaction between the soil physical climate and the soil biology and the corresponding above ground dynamics of plants. In connection to this the role of water for the dynamics of ecosystem is illustrated. Typical time scale for the studies have been shifting from minutes to around 100 years and the normal vertical scale is some cm of soil layer thickness. The spatial scale have been from regional scales, represented by typical ecosystems extended to 1000 km2 to small scales of some few m2. The role of the interaction and the need for considering also more components of an ecosystems are common when the time scales are extended from part of year to some decades. The strong control of winter conditions on turnover of forest growth is and the nitrogen and carbon dynamics is demonstrated by the carbon dynamics of forest ecosystems. Recent examples shows the potential with using uncertainty methods when illustrating also connection between models and data.
