ln_s_sh94 = .false. ! Song & Haidvogel 1994 hybrid S-sigma (T)|
ln_s_sf12 = .true. ! Siddorn & Furner 2012 hybrid S-z-sigma (T)| if both are false the NEMO tanh stretching is applied
ln_sigcrit = .true. ! use sigma coordinates below critical depth (T) or Z coordinates (F) for Siddorn & Furner stretch
! stretching coefficients for all functions
rn_jpk = 51 ! Number of S levels
ln_eq_taper = .false. ! Tapering of S coords near equator
cn_coord_hgr = 'coordinates.nc' ! File containing gphit (latitude) coordinate for use if ln_eq_taper=.true.
rn_sbot_min = 10.0 ! minimum depth of s-bottom surface (>0) (m)
rn_sbot_max = 7000.0 ! maximum depth of s-bottom surface (= ocean depth) (>0) (m)
rn_hc = 50.0 ! critical depth for transition to stretched coordinates
!!!!!!! Envelop bathymetry
rn_rmax = 0.3 ! maximum cut-off r-value allowed (0<r_max<1)
!!!!!!! SH94 stretching coefficients (ln_s_sh94 = .true.)
rn_theta = 6.0 ! surface control parameter (0<=theta<=20)

! bottom cell depth (Zb) is a linear function of water depth Zb = H*a + b
rn_zb_a = 0.024 ! bathymetry scaling factor for calculating Zb

!!!!!!!! Other stretching (not SH94 or SF12) [also uses rn_theta above]
