Annotated C++ source code of the LandClim beetle model

The .zip file contains three text files (beetle.cpp, climate.cpp and cohort.cpp) that contain the C++ source code for the beetle model implemented in LandClim. The code is annotated with references to variable names and equations in the published article. beetle.cpp contains the main routines of the beetle model, climate.cpp calculations of bioclimatic variables and cohort.cpp contains the routines used to simulate beetle-induced tree mortality.
