A round robin test for GLI (Global Imager) instrument was conducted with the three transfer spectrometers, 400-800 [nm], 500-1000 [nm] and 1300-2500 [nm] of the wavelength coverages, respectively. Also influence due to water vapor content in the integrating sphere of interest, in particular, at around 1400 [nm] of water vapor absorption band is evaluated. Using MODTRAN 3.7, it is found that the influence is approximately 40[%] for the relative humidity of 50 [%]. The absolute calibration accuracy of the integrating sphere was verified through a comparison of the radiance from the integrating sphere and the measured radiance with the transfer spectrometers. It is found that the difference between both shows around 1.5[%] for vibible to near infrared bands while approximately 2.5[%] for shortwave infrared bands.
