Distance weighted average remapping — cdo

This module contains operators for an inverse distance weighted average remapping of the four nearest neighbor values of fields between grids in spherical coordinates. The default number of 4 neighbors can be changed with the neighbors parameter.

Usage

cdo_gendis(ifile, grid = NULL, neighbors = NULL, map3d = NULL, ofile = NULL)

cdo_remapdis(ifile, grid = NULL, neighbors = NULL, map3d = NULL, ofile = NULL)

Arguments

ifile: String with the path to the input file.
grid: STRING - Target grid description file or name
neighbors: INTEGER - Number of nearest neighbors [default: 4]
map3d: BOOL - Generate all mapfiles of the first 3D field
ofile: String with the path to the output file.

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.

Details

remapdis  Distance weighted average remapping
          Performs an inverse distance weighted averaged remapping of the nearest neighbor values on all input fields.
gendis    Generate distance weighted average remap weights
          Generates distance weighted averaged remapping weights of the nearest neighbor values 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 &lt;outfile&gt;&lt;xxx&gt;.nc. xxx will have five digits with the number of the mapfile.
