On the sciences obtained from ADEOS-II mission

The scientific results, present status, and future plan of the ADEOS-II mission, especially for AMSR and GLI sensor, are presented in the paper. Five specific sensors aboard the ADEOS-II satellite were designed for making overall observation of land, atmosphere, ocean, and cryosphere from the sun-synchronous polar orbit. The AMSR and GLI are two of the primary sensors aboard the ADEOS-II satellite. The AMSR, a microwave scanner, retrieved the physical parameters related to global water cycle such as total precipitable water, cloud liquid water, precipitations and soil moisture. One the other hand, the GLI, a near ultraviolet to infrared imager, had captured many environmental events such as volcano eruptions, forest fires, and dust events with moderate spatial resolution of 250 m or 1 km. It also observed ocean colors, sea surface temperature, vegetation indices, aerosol and cloud properties, and precipitable water over land area. The ADEOS-II science activities continue in future. The primary objective of the next phase is the data utilization toward the future satellite missions, and the synergy of satellite data and climate models.
