R: Potential Temperature from Potential Enthalpy of Ice...

gsw_pt_from_pot_enthalpy_ice_poly {gsw} | R Documentation

## Potential Temperature from Potential Enthalpy of Ice (Polynomial version)

### Description

Potential Temperature from Potential Enthalpy of Ice (Polynomial version)

### Usage

    gsw_pt_from_pot_enthalpy_ice_poly(pot_enthalpy_ice)

### Arguments

`pot_enthalpy_ice` | potential enthalpy of ice [ J/kg ]

### Details

The present R function works with a wrapper to a C function contained within the GSW-C system (Version 3.05-4 dated 2017-08-07, available at https://github.com/TEOS-10/GSW-C, as git commit '5b4d959e54031f9e972f3e863f63e67fa4f5bfec'), which stems from the GSW-Fortran system (https://github.com/TEOS-10/GSW-Fortran) which in turn stems from the GSW-Matlab system (https://github.com/TEOS-10/GSW-Matlab).

### Value

potential temperature [ degC ]
