T-tendency due to horizontal diffusion (DTH) in CESM1.0

How is the T-tendency due to horizontal diffusion accounted for in CESM1? Prior to CCSM4, this could be outputted as variable DTH yet there appears to be no such variable for CESM1. Is it clumped in with the vertical diffusive heating term (DTV)?

Thank you!

  DTH is associated with the old Eulerian spectral atmosphere dynamical core.  In the current dynamical core (Finite Volume), horizontal diffusion is implicit and not a separable term. So it is not lumped in with DTV.  It is just considered part of dynamics.
