Early phase evaluations of GLI vicarious calibration factors for ocean-color channels

The GLI was launched on board the ADEOS-II on December 14, 2002. For the early phase evaluations of the observation radiances, the GLI calibration team carried out vicarious calibrations by using MOBY measurements. To achieve the calibrations, we used two methods, which utilize two near-infrared channels and the measurement of the aerosol optical thickness, to predict the aerosol optical properties. Applying these methods, we derived early GLI vicarious calibration factors for ocean-color channels.
