Detailed Description

Delivers methods for bicubic interpolation from a coarse regular grid on a fine regular grid.

This module delivers methods for bicubic interpolation from a coarse regular grid on a fine regular grid. Subroutines

• bcuint
• bcucof

are methods taken from

  W. H. Press, S. A. Teukolski, W. T. Vetterling and B. P. Flannery,
  Numerical Recipies in FORTRAN, The Art of Scientific Computing.

Version 1.0.0.2005-07-06 The module is thought to interact with MOM-4. Alle benotigten Felder werden extern von MOM verwaltet, da sie nicht fur alle interpolierten Daten die gleiche Dimension haben mussen.

Function/Subroutine Documentation

horiz_interp_bicubic_new_1d_()

subroutine horiz_interp_bicubic_new_1d_	(	type(horiz_interp_type), intent(inout)	Interp,
		real(fms_hi_kind_), dimension(:), intent(in)	lon_in,
		real(fms_hi_kind_), dimension(:), intent(in)	lat_in,
		real(fms_hi_kind_), dimension(:), intent(in)	lon_out,
		real(fms_hi_kind_), dimension(:), intent(in)	lat_out,
		integer, intent(in), optional	verbose,
		logical, intent(in), optional	src_modulo
	)

Creates a new horiz_interp_type.

Allocates space and initializes a derived-type variable that contains pre-computed interpolation indices and weights.

Definition at line 200 of file horiz_interp_bicubic.inc.

horiz_interp_bicubic_new_1d_s_()

subroutine horiz_interp_bicubic_new_1d_s_	(	type(horiz_interp_type), intent(inout)	Interp,
		real(fms_hi_kind_), dimension(:), intent(in)	lon_in,
		real(fms_hi_kind_), dimension(:), intent(in)	lat_in,
		real(fms_hi_kind_), dimension(:,:), intent(in)	lon_out,
		real(fms_hi_kind_), dimension(:,:), intent(in)	lat_out,
		integer, intent(in), optional	verbose,
		logical, intent(in), optional	src_modulo
	)

Creates a new horiz_interp_type.

Allocates space and initializes a derived-type variable that contains pre-computed interpolation indices and weights.

Parameters

[in,out]	interp	A derived-type variable containing indices and weights used for subsequent interpolations. To reinitialize this variable for a different grid-to-grid interpolation you must first use the HORIZ_INTERP_BICUBIC_NEW__del interface.
[in]	lon_in	Longitude (radians) for source data grid
[in]	lat_in	Latitude (radians) for source data grid
[in]	lon_out	Longitude (radians) for output data grid
[in]	lat_out	Latitude (radians) for output data grid
[in]	verbose	flag for print output amount
[in]	src_modulo	indicates if the boundary condition along zonal boundary is cyclic or not. Zonal boundary condition is cyclic when true
