cpl_mod.F90 @ 3627

Last change on this file since 3627 was 3627, checked in by lguez, 5 years ago
If the ocean skin parameterization is working (passively or actively, `activate_ocean_skin >= 1`) and we are coupled to the ocean then receive bulk salinity of the surface layer of the ocean from the ocean and feed it to procedure `bulk_flux` instead of the constant value 35. If the ocean skin parameterization is working actively (`activate_ocean_skin == 2`) and we are coupled to the ocean then send ocean-air interface temperature to the ocean. We can only send interface temperature from the previous time-step since communication with the ocean is before the call to `bulk_flux`. In module `cpl_mod`, define `cpl_t_int` with rank 1: no dimension for `cpl_index` because `t_int` is only defined over ocean. New dummy argument sss of procedures `cpl_receive_ocean_fields` and `ocean_cpl_noice`. New dummy argument `t_int` of `cpl_send_ocean_fields`. In procedure `surf_ocean`, rename local variable s1 to sss and give it the size klon, which is required by the coupling machinery.

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.
