Detailed Description

The coarse/fine face fluxes of the last RK stage, in the units the flux registers hold: (rho u)/m_uy, (rho v)/m_vx and the time-weighted (rho w)/(m_x m_y) without terrain; ax (rho u)/m_uy, ay (rho v)/m_vx and the time-weighted Omega/(m_x m_y) with it.

A coarse level records in rec[dir] the flux each substep applied through every face, and in rec_w the vertical quantity its z-faces hold at the end of the substep – (rho w) without terrain, Omega with it – and in rec_w_old the same at the start of the substep. A fine level takes the fluxes in tgt[dir] (component 0) on the faces where component 1 is one – its coarse/fine faces – in place of its own, and tgt_w as that vertical quantity there at the end of the substep. The fine level's fluxes through its boundary then add up to the coarse ones.
