39.7.2.2 Advection

Advection is diagnosed using the same advection operators used in the model for the chosen advection scheme. The contribution to locally referenced potential density takes the form

$$-(\rho_{\theta})_{i,k,j} \; ADV_{i,k,j,1} - (\rho_{s})_{i,k,j} \; ADV_{i,k,j,2}.$$ advrho_i,k,j = (39.98)

This term is computed inside of tracer.F. Note that the contribution from advection may include some dianeutral effects if using a dissipative advection scheme such as QUICKER or FCT.
