5 Exercises
5.1 Completing DYPTOP
The description of the model in Chapter 2 is incomplete. An additional point is considered for determining the flooded area fraction as a function of the water table depth in the work by Stocker, Spahni, and Joos (2014). Which one? Complement the model and revise Figure 2.5, visualising the additional constraint.

5.2 Improving the global peatland prediction
The predicted global distribution of the actual peatland area fraction shown in Figure 4.6 some major northern peatland complexes, including the Hudson Bay Lowland and the West Siberian Lowlands. In other regions, the map suggests excessive peatland areas (e.g., Amazon). Modify model parameters to improve the correspondence between predicted and observed global peatland areas. As observations, you may consider the global peatland map PEATMAP, shown e.g., here.
