16.1 Domain and Resolution

The model domain, which may be global, is defined as a thin shelled volume bounded by six coordinates: two latitudes, two longitudes, and two depths on the surface of a spherical earth. Embedded within this domain is a ``rectangular'' grid system aligned such that the principle directions are along longitude $\lambda$ (measured in degrees east of Greenwich), latitude $\phi$ (measured in degrees north of the equator), and depth zt (measured in centimeters from the surface of the spherical shell to the ocean bottom). Note that the vertical coordinate z increases upwards.
