311	! rk_tendency computes the large-timestep tendency terms in the
312	! momentum, thermodynamic (theta), and geopotential equations.
313	! These terms include:
314	!
315	! (1) advection (for u, v, w, theta - calls to advect_u, advect_v,
316	! advect_w, and advact_scalar).
317	!
318	! (2) geopotential equation terms (advection and "gw" - call to rhs_ph).
319	!
320	! (3) buoyancy term in vertical momentum equation (call to pg_buoy_w).
321	!
322	! (4) Coriolis and curvature terms in u,v,w momentum equations
323	! (calls to subroutines coriolis, curvature)
324	!
325	! (5) 3D diffusion on coordinate surfaces.

723	! (in *tend, these include advection, pressure gradient, etc;
