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.
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.
