Bicubic interpolation
remapbic.Rd
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)
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.
