5	! alloc_and_configure_domain 1. Allocate the space for a single domain (constants
6	! and null terminate pointers).
7	! 2. Connect the domains as a linked list.
8	! 3. Store all of the domain constants.
9	! 4. CALL alloc_space_field.
10
11	! alloc_space_field 1. Allocate space for the gridded data required for
12	! each domain.
13
14	! dealloc_space_domain 1. Reconnect linked list nodes since the current
15	! node is removed.
16	! 2. CALL dealloc_space_field.
17	! 3. Deallocate single domain.
18
19	! dealloc_space_field 1. Deallocate each of the fields for a particular
20	! domain.
21
22	! first_loc_integer 1. Find the first incidence of a particular
23	! domain identifier from an array of domain
24	! identifiers.

441	!<DESCRIPTION>
442	! Wrf_patch_domain is called as part of the process of initiating a new
443	! domain. Based on the global domain dimension information that is
444	! passed in it computes the patch and memory dimensions on this
445	! distributed-memory process for parallel compilation when DM_PARALLEL is
446	! defined in configure.wrf. In this case, it relies on an external
447	! communications package-contributed routine, wrf_dm_patch_domain. For
448	! non-parallel compiles, it returns the patch and memory dimensions based
449	! on the entire domain. In either case, the memory dimensions will be
450	! larger than the patch dimensions, since they allow for distributed
451	! memory halo regions (DM_PARALLEL only) and for boundary regions around
452	! the domain (used for idealized cases only). The width of the boundary
453	! regions to be accommodated is passed in as bdx and bdy.
454	!
455	! The bdy_mask argument is a four-dimensional logical array, each element
456	! of which is set to true for any boundaries that this process's patch
457	! contains (all four are true in the non-DM_PARALLEL case) and false
458	! otherwise. The indices into the bdy_mask are defined in
459	! frame/module_state_description.F. P_XSB corresponds boundary that
460	! exists at the beginning of the X-dimension; ie. the western boundary;
461	! P_XEB to the boundary that corresponds to the end of the X-dimension
462	! (east). Likewise for Y (south and north respectively).
463	!
464	! The correspondence of the first, second, and third dimension of each
465	! set (domain, memory, and patch) with the coordinate axes of the model
466	! domain is based on the setting of the variable model_data_order, which
467	! comes into this routine through USE association of
468	! module_driver_constants in the enclosing module of this routine,
469	! module_domain. Model_data_order is defined by the Registry, based on
470	! the dimspec entries which associate dimension specifiers (e.g. 'k') in
471	! the Registry with a coordinate axis and specify which dimension of the
472	! arrays they represent. For WRF, the sd1 , ed1 , sp1 , ep1 , sm1 , and
473	! em1 correspond to the starts and ends of the global, patch, and memory
474	! dimensions in X; those with 2 specify Z (vertical); and those with 3
475	! specify Y. Note that the WRF convention is to overdimension to allow
476	! for staggered fields so that sd<em>n</em>:ed<em>n</em> are the starts
477	! and ends of the staggered domains in X. The non-staggered grid runs
478	! sd<em>n</em>:ed<em>n</em>-1. The extra row or column on the north or

480	!
481	! The domdesc and parent_domdesc arguments are for external communication
482	! packages (e.g. RSL) that establish and return to WRF integer handles
483	! for referring to operations on domains. These descriptors are not set
484	! or used otherwise and they are opaque, which means they are never
485	! accessed or modified in WRF; they are only only passed between calls to
486	! the external package.

619
620	!<DESCRIPTION>
621	! This subroutine is used to allocate a domain data structure of
622	! TYPE(DOMAIN) pointed to by the argument <em>grid</em>, link it into the
623	! nested domain hierarchy, and set it's configuration information from
624	! the appropriate settings in the WRF namelist file. Specifically, if the
625	! domain being allocated and configured is nest, the <em>parent</em>
626	! argument will point to the already existing domain data structure for
627	! the parent domain and the <em>kid</em> argument will be set to an
628	! integer indicating which child of the parent this grid will be (child
629	! indices start at 1). If this is the top-level domain, the parent and
630	! kid arguments are ignored. <b>WRF domains may have multiple children
631	! but only ever have one parent.</b>
632	!
633	! The <em>domain_id</em> argument is the
634	! integer handle by which this new domain will be referred; it comes from
635	! the grid_id setting in the namelist, and these grid ids correspond to
636	! the ordering of settings in the namelist, starting with 1 for the
637	! top-level domain. The id of 1 always corresponds to the top-level
638	! domain. and these grid ids correspond to the ordering of settings in
639	! the namelist, starting with 1 for the top-level domain.
640	!
641	! Model_data_order is provide by USE association of
642	! module_driver_constants and is set from dimspec entries in the
643	! Registry.
644	!
645	! The allocation of the TYPE(DOMAIN) itself occurs in this routine.
646	! However, the numerous multi-dimensional arrays that make up the members
647	! of the domain are allocated in the call to alloc_space_field, after
648	! wrf_patch_domain has been called to determine the dimensions in memory
649	! that should be allocated. It bears noting here that arrays and code
650	! that indexes these arrays are always global, regardless of how the
651	! model is decomposed over patches. Thus, when arrays are allocated on a
652	! given process, the start and end of an array dimension are the global
653	! indices of the start and end of that process's subdomain.
654	!
655	! Configuration information for the domain (that is, information from the
656	! namelist) is added by the call to <a href=med_add_config_info_to_grid.html>med_add_config_info_to_grid</a>, defined
657	! in share/mediation_wrfmain.F.
