gsw_N2Osol

solubility of N2O in seawater

Contents

USAGE:

N2Osol = gsw_N2Osol(SA,CT,p,long,lat)

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:

SA  =  Absolute Salinity                                        [ g/kg ]
CT  =  Conservative Temperature                                [ deg C ]
p   =  sea pressure                                             [ dbar ]
       (i.e. absolute pressure - 10.1325 dbar)
long  =  longitude in decimal degrees                     [ 0 ... +360 ]
                                                   or  [ -180 ... +180 ]
lat   =  latitude in decimal degrees north               [ -90 ... +90 ]
SA & CT need to have the same dimensions. p, lat and long may have 
dimensions 1x1 or Mx1 or 1xN or MxN, where SA and CT are MxN.

OUTPUT:

N2Osol = solubility of nitrous oxide                         [ umol/kg ]

EXAMPLE:

SA = [34.7118; 34.8915; 35.0256; 34.8472; 34.7366; 34.7324;]
CT = [28.8099; 28.4392; 22.7862; 10.2262;  6.8272;  4.3236;]
p =  [     10;      50;     125;     250;     600;    1000;]
lat =  [      4;       4;       4;       4;       4;       4;]
long = [    188;     188;     188;     188;     188;     188;]
N2Osol = gsw_N2Osol(SA,CT,p,long,lat)
N2Osol =
