Vegetation carbon picture

Figure: Global distribution of vegetation carbon in the year 2000.

LPJmL is a dynamic global vegetation model (DGVM) with managed land use and river routing. It has been successfully parallelized using the message-passing library (MPI). The latest version is 4.0.002 and can be downloaded from a Github repository:

Additional information can be obtained from the LPJ & LPJmL Web Distribution Portal. The river routing part has been parallelized using a library for distributed networks (von Bloh, 2008; von Bloh et al., 2010).
