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. calib coef for nitrate n/a ==================================== conductivity calibration date 29 11 2016 temperature calibration date 29 11 2016 pressure calibration date 22 11 2016 flbbcd calibration date 30 11 2017 oxygen calibration date 12 04 2017 nitrate calibration date 19 07 2017 ocr calibration date 22 03 2018 float manufacturer NKE float serial number P41308-17CH001 PI FEI CHAI program name CHINA ARGO PROJECT principal investigator address SOED/CSIO, HANGZHOU originating country CHINA float deployer CHENGLONG LI float deployer address TIO/SOA, XIAMEN deployment type R/V deployment platform JIA GENG HAO deployment cruise id n/a profile at deployment n/a nominal drift pressure [dbar] 1000 cycles for drift pressure 1 nominal profile pressure [dbar] 1000 cycles for profile pressure 1 pump type n/a conductivity sensor type SBE41CP_V7.2.5 conductivity sensor manufacturer SBE conductivity sensor serial number 9210 conductivity sensor accuracy 0.005 conductivity sensor resolution 0.001 Profile Sampling Method continuous temperature sensor type SBE41CP_V7.2.5 temperature sensor manufacturer SBE temperature sensor serial number 9210 temperature sensor accuracy 0.002 temperature sensor resolution 0.001 pressure sensor type KISTLER_2900PSIA pressure sensor manufacturer KISTLER pressure sensor serial number 4940410 pressure sensor accuracy 2.4 pressure sensor resolution 0.1 oxygen sensor type AANDERAA_OPTODE_4330 oxygen sensor manufacturer AANDERAA oxygen sensor serial number 2781 oxygen sensor accuracy 8 oxygen sensor resolution 1 oxygen sensor pressure offset -0.5 oxygen sampling in air 1 chlorophyll sensor type ECO_FLBBCD chlorophyll sensor manufacturer WETLABS chlorophyll sensor serial number 4908 chlorophyll sensor accuracy 0.08 chlorophyll sensor resolution 0.025 chlorophyll sensor excit wavelength 470 chlorophyll sensor emission wavelength 695 backscattering sensor type ECO_FLBBCD backscattering sensor manufacturer WETLABS backscattering sensor serial number 4908 backscattering sensor accuracy -999.9 backscattering sensor resolution -999.9 backscattering sensor wavelength 700 backscattering sensor angle 124 backscattering sensor pressure offset 0.1 cdom sensor type ECO_FLBBCD cdom sensor manufacturer WETLABS cdom sensor serial number 4908 cdom sensor accuracy -999.9 cdom sensor resolution -999.9 cdom sensor excitation wavelength 370 cdom sensor emission wavelength 460 ocr sensor type SATLANTIC_OCR504_ICSW ocr sensor manufacturer SATLANTIC ocr sensor serial number 547 ocr sensor accuracy -999.9 ocr sensor resolution -999.9 ocr sensor bandwidth 10,10,10 ocr sensor wavelength 412,443,490 ocr sensor pressure offset -0.08 nitrate sensor type SUNA_V2 nitrate sensor manufacturer SATLANTIC nitrate sensor serial number 1032 nitrate sensor accuracy 2 nitrate sensor resolution 0.01 nitrate sensor pressure offset 1.5 nitrate calibration file SNA1032A.cal nitrate pixel start 36 nitrate pixel end 76 nitrate pixel fit start 36 nitrate pixel fit end 64 battery type Lithium initial battery voltage [volt] 10.8 board serial number C155136-0045 ROM version V3.1 comment n/a
