gsw_N2Osol_SP_pt
solubility of N2O in seawater
Contents
USAGE:
N2Osol = gsw_N2Osol_SP_pt(SP,pt)
DESCRIPTION:
Calculates the nitrous oxide, N2O, concentration expected at equilibrium
with air at an Absolute Pressure of 101325 Pa (sea pressure of 0 dbar)
including saturated water vapor. This function uses the solubility
coefficients as listed in Weiss and Price (1980).
Note that this algorithm has not been approved by IOC and is not work
from SCOR/IAPSO Working Group 127. It is included in the GSW
Oceanographic Toolbox as it seems to be oceanographic best practice.
INPUT:
SP = Practical Salinity (PSS-78) [ unitless ]
pt = potential temperature [ deg C ]
with reference sea pressure (pr) = 0 dbar.
SP & pt need to have the same dimensions.
OUTPUT:
N2Osol = solubility of nitrous oxide [ umol/kg ]
EXAMPLE:
SP = [34.7118; 34.8915; 35.0256; 34.8472; 34.7366; 34.7324;]
pt = [28.8099; 28.4392; 22.7862; 10.2262; 6.8272; 4.3236;]
N2Osol = gsw_N2Osol_SP_pt(SP,pt)
