FTS

FTS Radiometric Conversion for Band1-3

  Definitions:
    SPC = L1B spectrum [V/cm-1]
    RAD = Spectral radiance [W/cm2/str/cm-1]
    CNV = Radiometric conversion coefficient [W/cm2/str/cm-1/(V/cm-1)]
    WN = Wavenumber [cm-1]

  CNV file format ex. CNV(B1):
    WN(Band1), CNV(Band1P_gainH), CNV(Band1S_gainH), CNV(Band1P_gainM), CNV(Band1S_gainM)

  Conversion equation:
    RAD[WN] = SPC[WN] * CNV[WN]

  Caveats:
    August 8, 2016, Updated for V201.x
    (1) Band 1 (Gain_H) Modified amplitude and intensity dependent non-linearity correction + SINUC
    (2) Band 1 (Gain_M) Major Change: no more amplitude and intensity dependent non-linearity correction + SINUC
    (3) Band 2 + SINUC (Sampling Interval Non-Uniformity Correction), Low Frequency Correction, DC subtraction
    (4) Band 3 + SINUC, Low Frequency Correction, DC subtraction
    (5) Average of Forward and Backward

Spectral response function

 Definitions:
  WL = Wavelength [nm]
  SRF = Normalized spectral response function [a.u.]

 SRF file format ex. SRF(B1):
  WL(B1), SRF(B1)

 Caveats:
  April 23, 2009 (Algorithm Version: 006, Parameter Version: 006, Date: 090423)
  (1) SRF is evaluated by multiplying of filter optics transmittance and detector response.
  (2) Si CCDs are used for B1, B2 and B3, while InGaAs for B4.
