cpl_mod.F90 @ 3767

Last change on this file since 3767 was 3767, checked in by lguez, 4 years ago

Store delta_sal instead of s_int

Revision analoguous to revision [3744], for salinity. Store as a state
variable and send to the ocean delta_sal, the difference between
ocean-air interface salinity and bulk salinity, instead of s_int,
the interface salinity.

So replace dummy argument s_int of procedure cpl_send_ocean_fields
by dummy argument delta_sal. Replace dummy argument s_int of
procedures ocean_cpl_noice and surf_ocean by dummy argument
delta_sal. Replace variable s_int of module phys_state_var_mod
by variable delta_sal. Rename local variable ys_int of procedure
pbl_surface to ydelta_sal. Set variable delta_sal of module
phys_state_var_mod to 0 for an appearing ocean fraction and a
missing startup field. Replace variable o_s_int of module
phys_output_ctrlout_mod by variable o_delta_sal.

Rename variables cpl_s_int and cpl_s_int_2D of module cpl_mod to
cpl_delta_sal and cpl_delta_sal_2D. Rename variable ids_s_int of
module oasis to ids_delta_sal. Change infosend(ids_delta_sal)%name
to "CODELSSS".

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.
