19.3.2 Adding or removing surface boundary conditions

Look in module setup_sbc to see the list of possbile surface boundary conditions. The list can be extended indefinately. Then select the desired surface boundary conditions using a set of ordered calls in driver.F as indicated in Section 19.3. Alternatively, the set may be entered through namelist. If entering surface boundary condition names through namelist, make sure to enter the complete set of all names. The ordering of names determines how the surface boundary conditions will be stored. The only restrictions on ordering are:

Keep all surface boundary conditions for the ocean bundled together and put them first. Then bundle all surface boundary conditions for the atmosphere together and keep them last.
Within each bundle. Keep the ordering the same as the variables for which the surface boundary conditions are used. For instance, if there are six tracers, then keep the six tracer surface boundary conditions ordered the same way as the tracers.
