vertintgh: Vertical height interpolation

In rcdo: Wrapper of 'CDO' Operators

Vertical height interpolation

Description

Interpolate 3D variables on hybrid sigma height coordinates to height levels. The input file must contain the 3D geometric height in meter. The geometric height is identified by the NetCDF CF standard name geometric_height_at_full_level_center. Use the alias gh2hlx or the environment variable EXTRAPOLATE to extrapolate missing values. This operator requires all variables on the same horizontal grid.

Usage

cdo_gh2hl(ifile, hlevels = NULL, ofile = NULL)

Arguments

ifile	String with the path to the input file.
hlevels	FLOAT - Comma-separated list of height levels in meter
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.

Note

This is a specific implementation for NetCDF files from the ICON model, it may not work with data from other sources.
