remapbic: Bicubic interpolation

In rcdo: Wrapper of 'CDO' Operators

Bicubic interpolation

Description

This module contains operators for a bicubic remapping of fields between grids in spherical coordinates. The interpolation is based on an adapted SCRIP library version. For a detailed description of the interpolation method see SCRIP. This interpolation method only works on quadrilateral curvilinear source grids.

Usage

cdo_genbic(ifile, grid = NULL, map3d = NULL, ofile = NULL)

cdo_remapbic(ifile, grid = NULL, map3d = NULL, ofile = NULL)

Arguments

ifile	String with the path to the input file.
grid	STRING - Target grid description file or name
map3d	BOOL - Generate all mapfiles of the first 3D field
ofile	String with the path to the output file.

Details

remapbic  Bicubic interpolation
          Performs a bicubic interpolation on all input fields.
genbic    Generate bicubic interpolation weights
          Generates bicubic interpolation weights for the first input field and writes the
          result to a file. The format of this file is NetCDF following the SCRIP convention.
          Use the operator remap to apply this remapping weights to a data file with the same source grid.
          Set the parameter map3d=true to generate all mapfiles of the first 3D field with varying masks.
          In this case the mapfiles will be named <outfile><xxx>.nc. xxx will have five digits with the number of the mapfile.

Value

Operators that output one or more files return a character vector to the output files.

Operators that output an indefinite number of files return a string with the basename of the files.

Operatos that don't return filenames return a character vector with the string output.
