The Ntrans indices span the interval [PIXEL_START, PIXEL_END] subset of the original array (1 to 256). Thus Ntrans(i) refers to pixel N = (PIXEL_START+i-1). PIXEL_START and PIXEL_END are defined from calibration data so that the [PIXEL_START, PIXEL_END] interval is the smallest interval of pixels that correspond to the [217 nm, 250 nm] interval of wavelengths. Only a subset of the [PIXEL_START, PIXEL_END] interval is processed to compute nitrate concentration. This subset is defined as the [PIXEL_FIT_START, PIXEL_FIT_END] interval which is the smallest interval of pixels that correspond to the [217 nm, 240 nm] interval of wavelengths (thus PIXEL_FIT_START = PIXEL_START). In the following equations the data are computed for each pixel R = PIXEL_FIT_START to PIXEL_FIT_END; ABSORBANCE_SW(R)=-log10[(UV_INTENSITY_NITRATE(R)-UV_INTENSITY_DARK_NITRATE)/UV_INTENSITY_REF_NITRATE(R)]; F(R,T)=(A+B*T)*exp[(C+D*T)*(OPTICAL_WAVELENGTH_UV(R)-OPTICAL_WAVELENGTH_OFFSET)]; E_SWA_INSITU(R)=E_SWA_NITRATE(R)*F(R,TEMP)/F(R,TEMP_CAL_NITRATE); ABSORBANCE_COR_NITRATE(R)=ABSORBANCE_SW(R)-(E_SWA_INSITU(R)*PSAL)*[1-(0.026*PRES/1000)]; Perform a multilinear regression to get MOLAR_NITRATE with estimated ABSORBANCE_COR_NITRATE(R) with ABSORBANCE_COR_NITRATE(R)=BASELINE_INTERCEPT+BASELINE_SLOPE*OPTICAL_WAVELENGTH_UV(R)+MOLAR_NITRATE*E_NITRATE(R); NITRATE=MOLAR_NITRATE/rho, where rho is the potential density [kg/L] calculated from CTD data. none k0T=k0+k2*TEMP; pcorr=f1*PRES+f2*PRES^2+f3*PRES^3+f4*PRES^4+f5*PRES^5+f6*PRES^6; k0TP=k0T+pcorr; Tk=273.15+TEMP; Cltotal=(0.99889/35.453*PSAL/1.80655)/(1-0.001005*PSAL); ADH=3.4286e-6*TEMP^2+6.7524e-4*TEMP+0.49172143; IonS=19.924*PSAL/(1000-1.005*PSAL); log10gammaHCl=[-ADH*sqrt(IonS)/(1+1.394*sqrt(IonS))]+[(0.08885-0.000111*TEMP)*IonS]; deltaVHCl=17.85+0.1044*TEMP-0.001316*TEMP^2; log10gammaHCLtP=log10gammaHCl+[deltaVHCl*(PRES/10)/(R*Tk*ln(10))/2/10]; PH_IN_SITU_FREE=[(VRS_PH-k0TP)/(R*Tk/F*ln(10))]+[ln(Cltotal)/ln(10)]+2*log10gammaHCLtP-log10(1-0.001005*PSAL); Stotal=(0.14/96.062)*(PSAL/1.80655); Khso4=exp{[-4276.1/Tk+141.328-23.093*ln(Tk)]+[(-13856/Tk+324.57-47.986*ln(Tk))*IonS^0.5]+[(35474/Tk-771.54+114.723*ln(Tk))*IonS]-[2698/Tk*IonS^1.5]+[1776/Tk*IonS^2]+ln(1-0.001005*PSAL)}; deltaVHSO4=-18.03+0.0466*TEMP+0.000316*TEMP^2; KappaHSO4=(-4.53+0.09*TEMP)/1000; lnKhso4fac=(-deltaVHSO4+0.5*KappaHSO4*(PRES/10))*(PRES/10)/(R*10*Tk); Khso4TPS=Khso4*exp(lnKhso4fac); PH_IN_SITU_TOTAL=PH_IN_SITU_FREE-log10(1+Stotal/Khso4TPS) k0T=k0+k2*TEMP; pcorr=f1*PRES+f2*PRES^2+f3*PRES^3+f4*PRES^4+f5*PRES^5+f6*PRES^6; k0TP=k0T+pcorr; Tk=273.15+TEMP; Cltotal=(0.99889/35.453*PSAL/1.80655)/(1-0.001005*PSAL); ADH=3.4286e-6*TEMP^2+6.7524e-4*TEMP+0.49172143; IonS=19.924*PSAL/(1000-1.005*PSAL); log10gammaHCl=[-ADH*sqrt(IonS)/(1+1.394*sqrt(IonS))]+[(0.08885-0.000111*TEMP)*IonS]; deltaVHCl=17.85+0.1044*TEMP-0.001316*TEMP^2; log10gammaHCLtP=log10gammaHCl+[deltaVHCl*(PRES/10)/(R*Tk*ln(10))/2/10]; PH_IN_SITU_FREE=[(VRS_PH-k0TP)/(R*Tk/F*ln(10))]+[ln(Cltotal)/ln(10)]+2*log10gammaHCLtP-log10(1-0.001005*PSAL); Stotal=(0.14/96.062)*(PSAL/1.80655); Khso4=exp{[-4276.1/Tk+141.328-23.093*ln(Tk)]+[(-13856/Tk+324.57-47.986*ln(Tk))*IonS^0.5]+[(35474/Tk-771.54+114.723*ln(Tk))*IonS]-[2698/Tk*IonS^1.5]+[1776/Tk*IonS^2]+ln(1-0.001005*PSAL)}; deltaVHSO4=-18.03+0.0466*TEMP+0.000316*TEMP^2; KappaHSO4=(-4.53+0.09*TEMP)/1000; lnKhso4fac=(-deltaVHSO4+0.5*KappaHSO4*(PRES/10))*(PRES/10)/(R*10*Tk); Khso4TPS=Khso4*exp(lnKhso4fac); PH_IN_SITU_TOTAL=PH_IN_SITU_FREE-log10(1+Stotal/Khso4TPS) none none none none none ta0=6.868381e-04;ta1=2.559820e-04;ta2=2.299210e-07;ta3=1.132980e-07; Pcoef1=0.115, Pcoef2=0.00022, Pcoef3=0.0419; A0=1.0513, A1=-1.5e-03, A2=4.224030e-01; B0=-2.478210e-01, B1=1.653900e+00; C0=1.019150e-01, C1=4.343240e-03, C2=6.041100e-05;E=1.1e-02;Spreset=0; D0=24.4543, D1=-67.4509, D2=-4.8489, D3=-5.44e-4; SolB0=-6.24523e-3, SolB1=-7.37614e-3, SolB2=-1.03410e-3, SolB3=-8.17083e-3; SolC0=-4.88682e-7; none none none none SCALE_CHLA=1.677E-03;DARK_CHLA=50; DARK_BACKSCATTERING532=50;SCALE_BACKSCATTERING532=4.218E-07;khi=1.142;BETASW532 (contribution of pure sea water) is calculated at 150 deg; DARK_BACKSCATTERING700=50;SCALE_BACKSCATTERING700=3.632E-07;khi=1.142;BETASW700 (contribution of pure sea water) is calculated at 150 deg; none none none none none none n/a none R=8.31446;F=96485;k0=-1.3947;k2=-0.0010195;f0=-0.0017386;f1=1.316e-05;f2=-2.8678e-08;f3=3.4518e-11;f4=-2.2906e-14;f5=7.8801e-18;f6=-1.0919e-21; R=8.31446;F=96485;k0=-1.3947;k2=-0.0010195;f0=-0.0017386;f1=1.316e-05;f2=-2.8678e-08;f3=3.4518e-11;f4=-2.2906e-14;f5=7.8801e-18;f6=-1.0919e-21; .
