Simulating heterogeneous vegetation in climate models. Identifying when secondary vegetation becomes important
Abstract To parameterize the land surface in global climate models (GCMs) data must be provided at a variety of resolutions. In GCMs, high‐resolution data must be aggregated to the coarser resolution of the GCM. The method used for parameter aggregation can lead to the simulation of very different l...
