!WRF:DRIVER_LAYER:MAIN
!
!
! ESMF Application Wrapper for coupling WRF with a "dummy" component
! that simply reads SSTs from a file, sends to WRF, receives SST from
! WRF (two-way coupling). and checks that the SSTs match.
!
! This file contains the main program and associated modules for the
! SST "dummy" component and a simple coupler. It creates ESMF Gridded
! and Coupler Components.
!
! This source file is only built when ESMF coupling is used.
!
!
!
! Modules module_sst_component_top and module_sst_setservices define the
! "SST" dummy component.
!
MODULE module_sst_component_top
!
! This module defines sst_component_init1(), sst_component_init2(),
! sst_component_run1(), sst_component_run2(), and sst_component_finalize()
! routines that are called when SST is run as an ESMF component.

PROGRAM wrf_SST_ESMF
!
! ESMF Application Wrapper for coupling WRF with a "dummy" component
! that simply reads SSTs from a file and sends them to WRF (one-way
! coupling). Fields are returned from WRF to SST via the coupler for
! self-test only.
!
! Note that, like other WRF coupling methods (MCEL, MCT), ESMF coupling is
! supported only via auxiliary input and history streams.
!
! This is the main program that creates the ESMF Gridded and Coupler
! Component.
!
! "init" looks like this:
! 1. Init phase 1 for WRF, sets WRF exportState metadata for "time"
! and "domain" information needed by WRF IOAPI (which is called from
! the SST component). It also sets up all WRF and WSF modules. Note
! that this must be called before SST phase-1 init because SST uses
! WRF IOAPI.
! 2. Init phase 1 for SST, sets "time" metadata in SST exportState.
! 3. Initialize coupler, passing decomposition metadata from WRF exportState
! to SST importState.
! 4. Resolve any "time" metadata inconsistencies and create top-level clock.
! 5. Init phase 2 for SST, gets "domain" information from importState,
! creates an ESMF_Grid based on "domain" information using the exact same
! method as WRF (so WRF IOAPI calls will work), and sets up SST
! importState and exportState.
! 6. Init phase 2 for WRF, runs up to the end of the head_grid I/O "training"
! phase (done in med_before_solve_io()). This initializes WRF
! importState and exportState prior to the first coupling step during the
! "run" loop. Note that this only works for head_grid at present because
! recursion in WRF traversal of subdomains is not dealt with yet and
! because the code that populates the WRF importState and exportState is
! not yet sophisticated enough to handle creating and destroying nested
! domains at any time during the model run.
!TODO: ESMF auxio must begin at the start of the run. Remove this
!TODO: restriction later, if needed.
!
!TODO: Note that coupling is currently limited to one auxin plus one auxout
!TODO: streams. Extension to multiple pairs of auxio streams requires
!TODO: nested states (one for each auxio stream pair).
!TODO: For now, only support one input and/or one output stream via
!TODO: io_esmf. This condition is asserted in
!TODO: ext_esmf_open_for_read_begin() and
!TODO: ext_esmf_open_for_write_begin().
!
! "run" loop looks like this:
! 1. Run SST phase 1, reads SST from file and writes it to SST exportState
! for coupling to WRF.
! 2. Couple SST exportState -> WRF importState. First iteration: set up
! SST->WRF routeHandle via lazy evaluation.
! 3. Run WRF. First iteration: head_grid resumes after I/O "training"
! phase. Other iterations and domains: run normally.
! Read WRF importState and write WRF exportState (via med_before_solve_io()).
! Note that WRF assigns sst -> tsk for sea points in
! share/module_soil_pre.F.
! 4. Couple WRF exportState -> SST importState. First iteration: set up
! WRF->SST routeHandle via lazy evaluation.
! 5. Run SST phase 2, compare SST from file with SST from WRF (via
! SST importState) and error-exit if they differ.
! 6. Advance clock and goto step 1
!
! "finalize" is trivial, except for destruction of ESMF objects which is
! quite non-trivial at the moment.
