Namelist file cable.nml

The namelist file for CABLE is cable.nml. For offline applications it should be located in the directory in which you are running CABLE. For ACCESS cases, cable.nml should be located in ~/CABLE-AUX/UM on the machine that CABLE is being executed on.

The cable.nml file includes some settings that are common across all CABLE applications and others that are required only for offline applications. The following are annotated examples of cable.nml:

Note

If your namelist file has entries that do not appear here please check the obsolete and deprecated user features page.
