The ASTER Project established the ASTER Science Team comprised of Japanese and U.S. researchers in a wide spectrum of fields including geology, geological resources, meteorology, agriculture and forestry, and environmental science. ASTER Science Team takes initiative to define the purpose of ASTER Project and to coordinate its user requirements, which are the basis to define specifications for the sensors, the ground data processing systems, and sensor operations.
ASTER Science Team is separated with each working group (WG) according to research subject. Each WG member not only does individual research activities, but also participates in ASTER Science Team Meeting held in turn in Japan and U.S., and does adjustment of the progress of research and development, future research plan, total activities of ASTER Science Project.
The WGs of ASTER science project organized in Japan are as follows.
