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