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 Radiometric Conversion factor for V201 (Japanese)
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.For SRF file download : Click here
After the pointing mirror mechanism of TANSO-FTS was switched to its backup system on January 28, 2015. Mesh Pattern 3 in the GOSAT Standard Mesh Point (SMP) is selected for the standard mesh observation mode.
The coordinate data of SMP are available from the following link.
