Calculates potential density

This is a special operator for the post processing of the ocean and sea ice model MPIOM. It calculates the sea water potential density (name=rhopoto; code=18). Required input fields are sea water in-situ temperature (name=to; code=20) and sea water salinity (name=sao; code=5). Pressure is calculated from the level information or can be specified by the optional parameter.

Usage

cdo_rhopot(ifile, pressure = NULL, ofile = NULL)

Arguments

ifile

String with the path to the input file.

pressure

FLOAT - Pressure in bar (constant value assigned to all levels)

ofile

String with the path to the output file.
