This method is arbitrary. However, when solving this equation iteratively, it is important not to zero out SST from previous solutions over land areas. Their purpose is to act as a good initial guess to limit the iterations needed for subsequent solutions.

... window^19.22

Refer to Chapters 10 and 14. In CASE=0, the surface boundary conditions are zonally averaged time means. Since they are only functions of latitude, array does not exist and surface boundary conditions are set directly into arrays stf_i,j,n and smf_i,j,n.

... time^19.23

It should be noted that there is enough generality to accommodate datasets with other periods such as daily, hourly, etc and treat them as climatologies (periodic) or real data (non periodic). Also datasets with differing periods may be mixed. For example: climatological monthly SST may be used with hourly winds.

... constant^19.26

When using option implicit_free_surface the ocean volume is allowed to change. This allows for a fresh water flux to be used directly. This has not been implemented as of this writing. The recommendation is to set the salinity flux to zero and add fresh water flux directly to the free surface elevation.
