Welcome to the Globally Resolved Energy Balance (GREB) Climate Model, also known as the Monash Climate Model. This version has been customized for the Universidad Complutense of Madrid (GREB-UCM).

To compile this model, a fortran compiler such as gfortran must be installed already.
To plot results in R using the provided functions in output/,
R must be installed (http:https://cran.r-project.org/) along with the library "fields"
to be able to overlay country boundaries.
If R is already installed, the "fields" library can be installed by loading R and calling,
install.packages("fields")-
Download the repository to your computer (either using git or the .zip file). From the command line, go to the main model directory.
-
To compile greb-ucm with gfortran into the executable file
greb.x,make greb -
To run greb-ucm with the model output and parameters stored in the directory
output/test,./greb.x output/test -
Go to the main output directory,
cd output/ -
Call R from the output directory and load the model results using the example,
Rsource("example.r")
The following variables are output from the model with dimensions [nlon,nlat,ntime]
- Tmm : near surface temperature, monthly mean
- Tamm : atmospheric temperature, monthly mean
- Tomm : deep ocean temperature, monthly mean
- qmm : atmospheric moisture, monthly mean
- apmm : planetary albedo, monthly mean
