THE CEOS DATABASE : Missions, Instruments and Measurements
CEOS EO HANDBOOK – INSTRUMENT SUMMARY - ASTER -
Full Name Advanced Spaceborne Thermal Emission and Reflection Radiometer Status Operational
Instrument Agencies METI, NASA Maturity
Instrument Type High resolution optical imagers Geometry
Instrument Technology High resolution optical imager Sampling Imaging
Data Access Open Access Data Format HDF-EOS or GeoTiff
Measurements and Applications Surface and cloud imaging with high spatial resolution, stereoscopic observation of local topography, cloud heights, volcanic plumes, and generation of local surface digital elevation maps. Surface temperature and emissivity. ASTER SWIR detectors are no longer functioning due to anomalously high SWIR detector temperatures. ASTER SWIR data acquired since April 2008 are not useable, and show saturation of values and severe striping. All attempts to bring the SWIR bands back to life have failed, and no further action is envisioned.
