ADEOS-II calibration and validation plan

ADEOS-II is the second global observation satellite of Japan following ADEOS to improve satellite-based global change observation system, and to obtain Earth observation data set for elucidation of the global water and energy cycle, carbon cycle, stratospheric ozone depletion and so on. For these mission objectives, five remote sensing instruments are onboard ADEOS-II that was launched on December 14, 2002. NASDA is responsible to check out ADEOS-II, and to calibrate and validate AMSR and GLI sensor characteristics and their data products. After launch for four months, the first check out phase is planned for satellite function and performance and during the phase the first-light images of AMSR and GLI is obtained. Before data distribution for general uses, NASDA is planning the calibration and validation phase for eight months after the first check out phase. This paper describes overview of NASDA´s Calibration and Validation Plan.
