The instrument consists of (1) three visible and near-infrared channels (VNIR) between 0.5 and 0.9 micrometers at 15 meter resolution, (2) six shortwave infrared channels (SWIR) between 1.6 and 2.5 micrometers at 30 meter resolution, and (3) five thermal infrared channels (TIR) between 8 and 12 micrometers at 90 meter resolution. The instrument will have 4 % absolute radiometric accuracy in the VNIR and SWIR, and 2 K absolute thermal accuracy (240 to 370 K) over a 60 km swath whose center is pointable cross-track +/- 106 km. One of the VNIR channels will provide along cross-track stereo views with a base-to-height ratio of 0.6, which will be used for stereoscopic observations of local topography, cloud heights, volcanic plumes, and generating local digital elevation models (DEMs). Various combinations of VNIR, SWIR, and TIR will lead to (1) soil and rock studies, (2) volcano monitoring, (3) surface temperature, emissivity, and reflectivity, (4) land use patterns and vegetation monitoring, (5) evapotranspiration, land and ocean temperatures, and (6) glacier monitoring. The ASTER pointing capabilities will be such that any point on the globe would be accessible at least once every 16 days. The ASTER facility is provided by the Japanese Ministry of International Trade and Industry (MITI) and was flown on the NASA Earth Observing System (EOS) Terra satellite on December 18, 1999.
