Code changes to mom are limited to modifying the calculation and dimension of the Coriolis variable cori. Running the rotation driver will create the latitude data file needed to calculate the correct Coriolis terms, but the creation of all other data files is left to the researcher. The subroutine rot_intrp_sclr may be used to interpolate scalars (such as depths, surface tracers, etc.) while subroutine rot_intrp_vctr can be used to interpolate and correct the angles for vectors (such as wind stress).
