2	!!===================================================================
3	!! * crs.F90 *
4	!! Purpose: Interface for calculating quantities from a
5	!! higher-resolution grid for the coarse grid.
6	!!
7	!! Method: Given the user-defined reduction factor,
8	!! the averaging bins are set:
9	!! - nn_binref = 0, starting from the north
10	!! to the south in the model interior domain,
11	!! in this way the north fold and redundant halo cells
12	!! could be handled in a consistent manner and
13	!! the irregularities of bin size can be handled
14	!! more naturally by the presence of land
15	!! in the southern boundary. Thus the southernmost bin
16	!! could be of an irregular bin size.
17	!! Information on the parent grid is retained, specifically,
18	!! each coarse grid cell's volume and ocean surface
19	!! at the faces, relative to the parent grid.
20	!! - nn_binref = 1 (not yet available), starting
21	!! at a centralized bin at the equator, being only
22	!! truly centered for odd-numbered j-direction reduction
23	!! factors.

26	!! approach to accelerate simulations to steady-state

474	!! * SUBROUTINE crsfun_UV *
475	!! ** Purpose : Average, area-weighted, of U or V on the east and north faces
476	!!
477	!! ** Method : The U and V velocities (3D) are determined as the area-weighted averages
478	!! on the east and north faces, respectively,
479	!! of the parent grid subset comprising the coarse grid box.
480	!! In the case of the V and F grid, the last jrow minus 1 is spurious.
481	!! ** Inputs : p_e1_e2 = parent grid e1 or e2 (t,u,v,f)
482	!! cd_type = grid type (T,U,V,F) for scale factors; for velocities (U or V)
483	!! psgn = sign change over north fold (See lbclnk.F90)
484	!! p_pmask = parent grid mask (T,U,V,F) for scale factors;
485	!! for velocities (U or V)
486	!! p_fse3 = parent grid vertical level thickness (fse3u or fse3v)
487	!! p_pfield = U or V on the parent grid
488	!! p_surf_crs = (Optional) Coarse grid weight for averaging
489	!! ** Outputs : p_cfield3d = 3D field on coarse grid

1166	!! ** Purpose : Average, area-weighted, of U or V on the east and north faces
1167	!!
1168	!! ** Method : The U and V velocities (3D) are determined as the area-weighted averages
1169	!! on the east and north faces, respectively,
1170	!! of the parent grid subset comprising the coarse grid box.
1171	!! In the case of the V and F grid, the last jrow minus 1 is spurious.
1172	!! ** Inputs : p_e1_e2 = parent grid e1 or e2 (t,u,v,f)
1173	!! cd_type = grid type (T,U,V,F) for scale factors; for velocities (U or V)
1174	!! psgn = sign change over north fold (See lbclnk.F90)
1175	!! p_pmask = parent grid mask (T,U,V,F) for scale factors;
1176	!! for velocities (U or V)
1177	!! p_fse3 = parent grid vertical level thickness (fse3u or fse3v)
1178	!! p_pfield = U or V on the parent grid
1179	!! p_surf_crs = (Optional) Coarse grid weight for averaging
1180	!! ** Outputs : p_cfield3d = 3D field on coarse grid
1181	!!
1182	!! History. 29 May. completed draft.
