Performs spatial interpolation between grids using conservative interpolation.
This module can conservatively interpolate data from any logically rectangular grid to any rectangular grid. The interpolation scheme is area-averaging conservative scheme. There is an optional mask field for missing input data in both horiz_interp__conserveinit and horiz_interp_conserve. For efficiency purpose, mask should only be kept in horiz_interp_init (will remove the mask in horiz_interp in the future). There are 1-D and 2-D version of horiz_interp_conserve_init for 1-D and 2-D grid. There is a optional argument mask in horiz_interp_conserve_init_2d and no mask should to passed into horiz_interp_conserv. optional argument mask will not be passed into horiz_interp_conserve_init_1d and optional argument mask may be passed into horiz_interp_conserve (For the purpose of reproduce Memphis??? results). An optional output mask field may be used in conjunction with the input mask to show where output data exists.
| interface horiz_interp_conserve_mod::horiz_interp_conserve_new |
Allocates space and initializes a derived-type variable that contains pre-computed interpolation indices and weights.
Allocates space and initializes a derived-type variable that contains pre-computed interpolation indices and weights for improved performance of multiple interpolations between the same grids.
| lon_in | Longitude (in radians) for source data grid. |
| lat_in | Latitude (in radians) for source data grid. |
| lon_out | Longitude (in radians) for destination data grid. |
| lat_out | Latitude (in radians) for destination data grid. |
| verbose | flag for the amount of print output. |
| mask_in | Input mask. must be the size (size(lon_in)-1, size(lon. The real value of mask_in must be in the range (0.,1.). Set mask_in=0.0 for data points that should not be used or have missing data. |
| mask_out | Output mask that specifies whether data was computed. |
| 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_del" interface. |

Subroutine for performing the horizontal interpolation between two grids.
Subroutine for performing the horizontal interpolation between two grids. horiz_interp_conserve_new must be called before calling this routine.
| [in] | data_in | Input data on source grid |
| [out] | data_out | Output data on destination grid |
| [in] | verbose | 0 = no output; 1 = min,max,means; 2 = max output |
| [in] | mask_in | Input mask, must be the same size as the input data. The real value of mask_in must be in the range (0.,1.). Set mask_in=0.0 for data points that should not be used or have missing data. mask_in will be applied only when horiz_interp_conserve_new_1d is called. mask_in will be passed into horiz_interp_conserve_new_2d |
| [out] | mask_out | Output mask that specifies whether data was computed. mask_out will be computed only when horiz_interp_conserve_new_1d is called. mask_out will be computed in horiz_interp_conserve_new_2d |

| subroutine, public horiz_interp_conserve_mod::horiz_interp_conserve_del | ( | type (horiz_interp_type), intent(inout) | Interp | ) |
Deallocates memory used by "HI_KIND_TYPE" variables. Must be called before reinitializing with horiz_interp_new.
| [in,out] | interp | A derived-type variable returned by previous call to horiz_interp_new. The input variable must have allocated arrays. The returned variable will contain deallocated arrays. |
