FBM 2.1

P: The Frankfurt Biosphere model (FBM) is a process oriented global vegetation model on a 0.5ox0.5o grid to compute the net primary productivity (NPP) and standing biomasses dependent on climate and soil properties.

b) SCENGEN: a model to obtain the regional distribution of the damage of climate change, reproducing a possible set of regional patterns which correspond to different GCM results.
The MiniCAM computes the GHG-emissions, temperature change, sea level rise, and market and non-market damage of climate change.
