!! ** Method/usage :
!! The control surface can be either a mixed layer depth (time varying)
!! or a fixed surface (jk level or bowl).
!! Choose control surface with nctls_trc in namelist NAMTRD :
!! nctls_trc = -2 : use isopycnal surface
!! nctls_trc = -1 : use euphotic layer with light criterion
!! nctls_trc = 0 : use mixed layer with density criterion
!! nctls_trc = 1 : read index from file 'ctlsurf_idx'
!! nctls_trc > 1 : use fixed level surface jk = nctls_trc
!! Note: in the remainder of the routine, the volume between the
!! surface and the control surface is called "mixed-layer"

!!----------------------------------------------------------------------
!! *** ROUTINE trd_mxl_trc ***
!!
!! ** Purpose : Compute and cumulate the mixed layer trends over an analysis
!! period, and write NetCDF outputs.
!!
!! ** Method/usage :
!! The stored trends can be chosen twofold (according to the ln_trdmxl_trc_instant
!! logical namelist variable) :
!! 1) to explain the difference between initial and final
!! mixed-layer T & S (where initial and final relate to the
!! current analysis window, defined by ntrc_trc in the namelist)
!! 2) to explain the difference between the current and previous
!! TIME-AVERAGED mixed-layer T & S (where time-averaging is
!! performed over each analysis window).
!!
!! ** Consistency check :
!! If the control surface is fixed ( nctls_trc > 1 ), the residual term (dh/dt
!! entrainment) should be zero, at machine accuracy. Note that in the case
!! of time-averaged mixed-layer fields, this residual WILL NOT BE ZERO
!! over the first two analysis windows (except if restart).
!! N.B. For ORCA2_ICE, use e.g. ntrc_trc=5, rn_ucf_trc=1., nctls_trc=8
!! for checking residuals.
!! On a NEC-SX5 computer, this typically leads to:
!! O(1.e-20) temp. residuals (tml_res) when ln_trdmxl_trc_instant=.false.
!! O(1.e-21) temp. residuals (tml_res) when ln_trdmxl_trc_instant=.true.
!!
!! ** Action :
!! At each time step, mixed-layer averaged trends are stored in the
!! tmltrd(:,:,jpmxl_xxx) array (see trdmxl_oce.F90 for definitions of jpmxl_xxx).
!! This array is known when trd_mld is called, at the end of the stp subroutine,
!! except for the purely vertical K_z diffusion term, which is embedded in the
!! lateral diffusion trend.
!!
!! In I), this K_z term is diagnosed and stored, thus its contribution is removed
!! from the lateral diffusion trend.
!! In II), the instantaneous mixed-layer T & S are computed, and misc. cumulative
!! arrays are updated.
!! In III), called only once per analysis window, we compute the total trends,
!! along with the residuals and the Asselin correction terms.
!! In IV), the appropriate trends are written in the trends NetCDF file.
