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.

Note

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