GREB model code


The FORTRAN code for the GREB model has been published together with the article in Climate Dynamics. The model is relatively simple, with just 771 lines of code. Have a look at the code:


Below we provide an optimised FORTRAN code which runs faster. It computes about 1-2yrs simulation per second, so about 100,000yrs simulation per 24hrs CPU time. It is numerically different from the original code, but identical in the physics.

The following archive file contains the model code and all input files (e.g. solar radiation, topography, etc) needed to run the model:

Good Luck with running the model!
