Ongoing PILPS Science Questions
1. What is the ability of the models to reproduce the water, energy, and carbon exchanges in semi-arid environments?
2. Are the current (usually single) representations of semi-arid lands in the models enough to reproduce the different environments that exist in those areas?
3. Does model calibration reduce the among-model range in the model simulations?
4. How much influence does the model parameterization have on the parameter estimations of “physically meaningful” parameters?
5. Do current carbon representations, developed for forests, properly reproduce carbon exchanges over vegetated arid lands?
