gsw_pt_from_pot_enthalpy_ice_poly
potential temperature of ice with a reference sea
pressure of zero dbar from the potential enthalpy
of ice
Contents
USAGE:
pt0_ice = gsw_pt_from_pot_enthalpy_ice_poly(pot_enthalpy_ice)
DESCRIPTION:
Calculates the potential temperature of ice from the potential enthalpy
of ice. The reference sea pressure of both the potential temperature
and the potential enthalpy is zero dbar. This is a compuationally
efficient polynomial fit to the potential enthalpy of ice.
INPUT:
pot_enthalpy_ice = potential enthalpy of ice [ J/kg ]
OUTPUT:
pt0_ice = potential temperature of ice [ deg C ]
with reference sea pressure (pr) = 0 dbar.
Note. The reference sea pressure of the output, pt, is zero dbar.
EXAMPLE:
pot_enthalpy_ice = [-3.5544e5; -3.6033e5; -3.5830e5; -3.5589e5; -3.4948e5; -3.4027e5;]
pt0_ice = gsw_pt_from_pot_enthalpy_ice_poly(pot_enthalpy_ice)
