vertintap: Vertical pressure interpolation

In rcdo: Wrapper of 'CDO' Operators

Vertical pressure interpolation

Description

Interpolate 3D variables on hybrid sigma height coordinates to pressure levels. The input file must contain the 3D air pressure in pascal. The air pressure is identified by the NetCDF CF standard name air_pressure. Use the alias ap2plx or the environment variable EXTRAPOLATE to extrapolate missing values. This operator requires all variables on the same horizontal grid.

Usage

cdo_ap2pl(ifile, plevels = NULL, ofile = NULL)

Arguments

ifile	String with the path to the input file.
plevels	FLOAT - Comma-separated list of pressure levels in pascal
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.
