Download CAM source code and datasets from.
http://www.ccsm.ucar.edu/models/atm-cam/
The download of the source code is called "cam2.0.2_source.tar.gz" and the
download of the datasets is called "cam2.0.2_standard_datasets.tar.gz".
-
Untar the standard datasets (to run at other resolutions or with other
dynamics you will need to also untar the "non-standard" dataset.
gunzip -c cam2.0.2.standard_datasets.tar.gz | tar xvf -
-
Set the environment variable "CSMDATA" to the location of the input datasets.
setenv CSMDATA `pwd`/inputdata
-
Go to the location you want to store the source code and untar the source-code.
gunzip -c cam2.0.2.source.tar.gz | tar xvf -

Do a simple run on the NCAR IBM with the "run-ibm.pl" script (if
not running on the NCAR IBM you will need to edit this script). If
you want to run on a different machine there are scripts for the IBM,
SGI or Linux-PC platforms that can be modified for your specific
machine in question. The run-ibm.csh and run-sgi.csh scripts both
have batch information in them that allow them to be run either interactively
or in the NCAR batch-queue.
cd cam2/models/atm/cam/bld
run-ibm.csh
At this point the model should begin compiling and executing. Appropriate
log files will be generated in the
