MODULE sbccpl
!!======================================================================
!! *** MODULE sbccpl ***
!! Surface Boundary Condition : momentum, heat and freshwater fluxes in coupled mode
!!======================================================================
!! History : 2.0 ! 2007-06 (R. Redler, N. Keenlyside, W. Park) Original code split into flxmod & taumod
!! 3.0 ! 2008-02 (G. Madec, C Talandier) surface module
!! 3.1 ! 2009_02 (G. Madec, S. Masson, E. Maisonave, A. Caubel) generic coupled interface
!! 3.4 ! 2011_11 (C. Harris) more flexibility + multi-category fields
!! 4.2 ! 2020-12 (G. Madec, E. Clementi) wave coupling updates
!!----------------------------------------------------------------------
!!----------------------------------------------------------------------
!! namsbc_cpl : coupled formulation namlist
!! sbc_cpl_init : initialisation of the coupled exchanges
!! sbc_cpl_rcv : receive fields from the atmosphere over the ocean (ocean only)
!! receive stress from the atmosphere over the ocean (ocean-ice case)
!! sbc_cpl_ice_tau : receive stress from the atmosphere over ice
!! sbc_cpl_ice_flx : receive fluxes from the atmosphere over ice
!! sbc_cpl_snd : send fields to the atmosphere

!!----------------------------------------------------------------------
!! *** ROUTINE sbc_cpl_rcv ***
!!
!! ** Purpose : provide the stress over the ocean and, if no sea-ice,
!! provide the ocean heat and freshwater fluxes.
!!
!! ** Method : - Receive all the atmospheric fields (stored in frcv array). called at each time step.
!! OASIS controls if there is something do receive or not. nrcvinfo contains the info
!! to know if the field was really received or not
!!
!! --> If ocean stress was really received:
!!
!! - transform the received ocean stress vector from the received
!! referential and grid into an atmosphere-ocean stress in
!! the (i,j) ocean referencial and at the ocean velocity point.
!! The received stress are :
!! - defined by 3 components (if cartesian coordinate)
!! or by 2 components (if spherical)
!! - oriented along geographical coordinate (if eastward-northward)
!! or along the local grid coordinate (if local grid)
!! - given at U- and V-point, resp. if received on 2 grids
!! or at T-point if received on 1 grid
!! Therefore and if necessary, they are successively
!! processed in order to obtain them
!! first as 2 components on the sphere
!! second as 2 components oriented along the local grid
!! third as 2 components on the U,V grid
!!
!! -->
!!
!! - In 'ocean only' case, non solar and solar ocean heat fluxes
!! and total ocean freshwater fluxes
!!
!! ** Method : receive all fields from the atmosphere and transform
!! them into ocean surface boundary condition fields
!!
!! ** Action : update utau, vtau ocean stress at U,V grid
!! taum wind stress module at T-point
!! wndm wind speed module at T-point over free ocean or leads in presence of sea-ice
!! qns non solar heat fluxes including emp heat content (ocean only case)
!! and the latent heat flux of solid precip. melting
!! qsr solar ocean heat fluxes (ocean only case)
!! emp upward mass flux [evap. - precip. (- runoffs) (- calving)] (ocean only case)

!!
!! ** Purpose : provide the stress over sea-ice in coupled mode
!!
!! ** Method : transform the received stress from the atmosphere into
!! an atmosphere-ice stress in the (i,j) ocean referencial
!! and at the velocity point of the sea-ice model:
!! 'C'-grid : i- (j-) components given at U- (V-) point
!!
!! The received stress are :
!! - defined by 3 components (if cartesian coordinate)
!! or by 2 components (if spherical)
!! - oriented along geographical coordinate (if eastward-northward)
!! or along the local grid coordinate (if local grid)
!! - given at U- and V-point, resp. if received on 2 grids
!! or at a same point (T or I) if received on 1 grid
!! Therefore and if necessary, they are successively
!! processed in order to obtain them
!! first as 2 components on the sphere
!! second as 2 components oriented along the local grid
!! third as 2 components on the ice grid point
!!
!! Except in 'oce and ice' case, only one vector stress field
!! is received. It has already been processed in sbc_cpl_rcv
!! so that it is now defined as (i,j) components given at U-
!! and V-points, respectively.

SUBROUTINE sbc_cpl_ice_flx( kt, picefr, palbi, psst, pist, phs, phi )
!!----------------------------------------------------------------------
!! *** ROUTINE sbc_cpl_ice_flx ***
!!
!! ** Purpose : provide the heat and freshwater fluxes of the ocean-ice system
!!
!! ** Method : transform the fields received from the atmosphere into
!! surface heat and fresh water boundary condition for the
!! ice-ocean system. The following fields are provided:
!! * total non solar, solar and freshwater fluxes (qns_tot,
!! qsr_tot and emp_tot) (total means weighted ice-ocean flux)
!! NB: emp_tot include runoffs and calving.
!! * fluxes over ice (qns_ice, qsr_ice, emp_ice) where
!! emp_ice = sublimation - solid precipitation as liquid
!! precipitation are re-routed directly to the ocean and
!! calving directly enter the ocean (runoffs are read but included in trasbc.F90)
!! * solid precipitation (sprecip), used to add to qns_tot
!! the heat lost associated to melting solid precipitation
!! over the ocean fraction.
!! * heat content of rain, snow and evap can also be provided,
!! otherwise heat flux associated with these mass flux are
!! guessed (qemp_oce, qemp_ice)
!!
!! - the fluxes have been separated from the stress as
!! (a) they are updated at each ice time step compare to
!! an update at each coupled time step for the stress, and
!! (b) the conservative computation of the fluxes over the
!! sea-ice area requires the knowledge of the ice fraction
!! after the ice advection and before the ice thermodynamics,
!! so that the stress is updated before the ice dynamics
!! while the fluxes are updated after it.
!!
!! ** Details
!! qns_tot = (1-a) * qns_oce + a * qns_ice => provided
!! + qemp_oce + qemp_ice => recalculated and added up to qns
!!
!! qsr_tot = (1-a) * qsr_oce + a * qsr_ice => provided
!!
!! emp_tot = emp_oce + emp_ice => calving is provided and added to emp_tot (and emp_oce).
!! runoff (which includes rivers+icebergs) and iceshelf
!! are provided but not included in emp here. Only runoff will
!! be included in emp in other parts of NEMO code
!!
!! ** Note : In case of the ice-atm coupling with conduction fluxes (such as Jules interface for the Met-Office),
!! qsr_ice and qns_ice are not provided and they are not supposed to be used in the ice code.
!! However, by precaution we also "fake" qns_ice and qsr_ice this way:
!! qns_ice = qml_ice + qcn_ice ??
!! qsr_ice = qtr_ice_top ??
!!
!! ** Action : update at each nf_ice time step:
!! qns_tot, qsr_tot non-solar and solar total heat fluxes
!! qns_ice, qsr_ice non-solar and solar heat fluxes over the ice
!! emp_tot total evaporation - precipitation(liquid and solid) (-calving)
!! emp_ice ice sublimation - solid precipitation over the ice
!! dqns_ice d(non-solar heat flux)/d(Temperature) over the ice
!! sprecip solid precipitation over the ocean
