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

!! ** Method : 1) SUM. For grid types T,U,V,F (and W) the 2D scale factors of

!! The fractions of masked:total surface (3D) on the east,

!! - e1,e2 Scale factors
!! Valid arguments:
!! 2) VOL. For grid types W and T, the coarse grid box
!! volumes are output. Also optionally, the fraction of
!! masked:total volume of the parent grid subset is output (i.e. facvol).
!! 3) WGT. Based on the grid type, the denominator is pre-determined here to
!! perform area- or volume- weighted averages,
!! to avoid IF-tests and divisions.
!! ** Inputs : p_e1, p_e2 = parent grid e1 or e2 (t,u,v,f)

!! *** SUBROUTINE crsfun_UV ***
!! ** Purpose : Average, area-weighted, of U or V on the east and north faces
!!
!! ** Method : The U and V velocities (3D) are determined as the area-weighted averages
!! on the east and north faces, respectively,
!! of the parent grid subset comprising the coarse grid box.
!! In the case of the V and F grid, the last jrow minus 1 is spurious.
!! ** Inputs : p_e1_e2 = parent grid e1 or e2 (t,u,v,f)
!! cd_type = grid type (T,U,V,F) for scale factors; for velocities (U or V)
!! psgn = sign change over north fold (See lbclnk.F90)
!! p_pmask = parent grid mask (T,U,V,F) for scale factors;
!! for velocities (U or V)
!! p_e3 = parent grid vertical level thickness (e3u or e3v)
!! p_pfield = U or V on the parent grid
!! p_surf_crs = (Optional) Coarse grid weight for averaging
!! ** Outputs : p_cfield3d = 3D field on coarse grid
!!
!! History. 29 May. completed draft.
!! 4 Jun. Revision for WGT
!! 5 Jun. Streamline for area-weighted average only ; separate scale factor and weights.
