cpl_mod.F90 @ 3628

Last change on this file since 3628 was 3628, checked in by lguez, 4 years ago
If the ocean skin parameterization is working actively (`activate_ocean_skin == 2`) and we are coupled to the ocean then send ocean-air interface salinity to the ocean. New dummy argument `s_int` of procedures `ocean_cpl_noice` and `cpl_send_ocean_fields`. We can only send interface salinity from the previous time-step since communication with the ocean is before the call to bulk_flux. So make `s_int` a state variable: move `s_int` from `phys_output_var_mod` to `phys_state_var_mod`. Still, we only read `s_int` from startphy, define it before the call to `surf_ocean` and write it to restartphy if `activate_ocean_skin == 2` and `type_ocean == 'couple'`. In procedure `pbl_surface`, for clarity, move the definition of output variables `t_int`, dter, dser, tkt, tks, rf, taur to `missing_val` to after the call to `surf_ocean`, with the definition of `s_int`, `ds_ns`, `dt_ns` to `missing_val`. This does not change anything for `t_int`, dter, dser, tkt, tks, rf, taur. In `pbl_surface_newfrac`, we choose to set `s_int` to 35 for an appearing ocean point, this is questionable. In `surf_ocean`, change the intent of `s_int` from out to inout.

2	MODULE cpl_mod
3	!
4	! This module excahanges and transforms all fields that should be recieved or sent to
5	! coupler. The transformation of the fields are done from the grid 1D-array in phylmd
6	! to the regular 2D grid accepted by the coupler. Cumulation of the fields for each
7	! timestep is done in here.
8	!
9	! Each type of surface that recevie fields from the coupler have a subroutine named
10	! cpl_receive_XXX_fields and each surface that have fields to be sent to the coupler
11	! have a subroutine named cpl_send_XXX_fields.
