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. k0T=k0+k2*TEMP; pcorr=f1*PRES+f2*PRES^2+f3*PRES^3+f4*PRES^4; 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) DOWN_IRRADIANCE443=0.01*A1_443*(RAW_DOWNWELLING_IRRADIANCE443-A0_443)*lm_443; DOWN_IRRADIANCE490=0.01*A1_490*(RAW_DOWNWELLING_IRRADIANCE490-A0_490)*lm_490; DOWNWELLING_PAR=A1_PAR*(RAW_DOWNWELLING_PAR-A0_PAR)*lm_PAR; none none none c0=2.71132E-03;c1=1.15379E-04;c2=2.41916E-06;c3=1.51821E02;c4=-2.43877E-01;c5=-3.96436E01;c6=2.99413E00; SCALE_CHLA=0.0073;DARK_CHLA=47; DARK_BACKSCATTERING700=48;SCALE_BACKSCATTERING700=1.861E-06;khi=1.076;BETASW700 (contribution of pure sea water) is calculated at 124 deg; SCALE_CDOM=0.0903;DARK_CDOM=47; A1_412=1.9514449557e-007;A0_412=2147560409.5;lm_412=1.368; n/a R=8.31446;F=96485;k0=-1.397769;k2=-9.6301E-04;f0=3.2819E-03;f1=3.9434E-06;f2=1.0559E-09;f3=-1.7851E-12;f4=4.5804E-16; A1_443=1.9932780741e-007;A0_443=2148248837.3;lm_443=1.410; A1_490=2.02067246045e-007;A0_490=2149969228.3;lm_490=1.365; A1_PAR=3.57379547974e-006;A0_PAR=2147957021.4;lm_PAR=1.359; none none L none none none Sullivan et al., 2013, Zhang et al., 2009, BETASW700 is the contribution by the pure seawater at 700nm, requiring temperature, salinity and using a depolarization of 0.039, its default value. the script can be found at http://doi.org/10.17882/42916.
