! --- depth (z or sigma). layer 1 is always fixed, so isotop=0.0 is not
! --- allowed. if isotop<0.0 then isotop(1:idm,1:jdm) is a spatially
! --- varying array, input from the file iso.top.[ab].
!
! --- away from the surface, the minimum layer thickness is dp00i.
! --- to recover original hybrid behaviour, set dp00i=dp00x
! --- for z-only, sigma-only or sigma-z only, set dp00i=dp00x
!
! --- for z-only set nsigma=0 (and ds00,ds00x,ds00f=dp00,dp00x,dp00f)
! --- for sigma-z (shallow-deep) use a very small ds00
! --- (pure sigma-z also has ds00f=dp00f and ds00x=dp00x*ds00/dp00)
! --- for z-sigma (shallow-deep) use a very large dp00 (not recommended)
! --- for sigma-only set nsigma=kdm, dp00 large, and ds00 small
!
! --- for an entirely fixed vertical coordinate (no isopycnal layers), set
! --- isotop large or make all target densities (sigma(k), below) very small.
!
! --- or, in place of 'd?00','d?00x','d?00f' specify:
! --- 'dx0k ' = layer k maximum layer thickness (m)
! --- 'dp0k ' = layer k deep z-level spacing minimum thickness (m)
! --- k=1,kdm; dp0k must be zero for k>nhybrd
! --- 'ds0k ' = layer k shallow z-level spacing minimum thickness (m)
! --- k=1,nsigma
!
! --- uses version 2.2.58 definition of deep and shallow z-levels.
! --- terrain following starts at depth dpns=sum(dp0k(k),k=1,nsigma) and
! --- ends at depth dsns=sum(ds0k(k),k=1,nsigma), and the depth of the
! --- k-th layer interface varies linearly with total depth between
! --- these two reference depths.
!
! --- previous to 2.2.58, it was layer thickness (not layer interface
! --- depth) that varied linearly with total depth. These two approachs
! --- are identical for "pure sigma-z", but differ if ds00f/=dp00f.
!
! --- dx0* is optional, and is disabled if not present. It "inflates"
! --- zero thickness layers at the bottom if the layer above is thicker
! --- than its maximum. This replaces very thick isopycnal layers with
! --- several thinner layers that might still have about the same
! --- density but can have different velocities. Hence increasing the
! --- deep vertical resolution. The idea behind dx0k comes from
! --- MOM6's HYCOM1 option MAX_LAYER_THICKNESS.
