! ntbtts = number of tracer term balance time steps
! tbt = time averagred term balances of tracers
! (1) = total time rate of change for the tracer
! (2) = change due to zonal nonlinear term (UT)x
! (3) = change due to meridional nonlinear term (VT)y
! (4) = change due to vertical nonlinear term (WT)z
! (5) = change due to zonal diffusion: Ah*Txx
! (6) = change due to meridional diffusion: Ah*Tyy
! (7) = change due to vertical diffusion: kappa_h*Tzz
! (8) = change due to source term
! (9) = change due to explicit convection
! (10) = change due to filtering
! (11) = average tracer within volume (tracer units)
