ASTER (Advanced Spaceborne Thermal Emission and Reflection radiometer) is the high efficiency optical imager which covers a wide spectral region from the visible to the thermal infra-red by 14 spectral bands. ASTER acquires data which can be used in various fields in earth science. ASTER was launched from Vandenberg Air Force Base in California, USA in 1999 aboard the Terra, which is the first satellite of the EOS Project. The purpose of ASTER project is to make contributions to extend the understanding of local and regional phenomena on the Earth surface and its atmosphere. The followings are ASTER related information, which includes ASTER instrument, ASTER Ground Data System, ASTER Science Activities, ASTER Data Distribution and so on.
