CEOS Instrument: Advanced Spaceborne Thermal Emission and Reflection Radiometer




Instrument:ASTER
Agencies: METI [Primary]
 NASA
Mission: Terra
Status:Operational
Type:High resolution optical imager
Description: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
Spatial Resolution: VNIR: 15 m, stereo: 15 m horizontally and 25 m vertical, SWIR: 30 m, TIR: 90 m
Swath Width: 60 km
Wavebands: VIS and NIR: 3 bands in 0.52 - 0.86 ?m, SWIR: 6 bands in 1.6 - 2.43 ?m, TIR: 5 bands in 8.125 - 11.65 ?m
Technology: High resolution optical imager
Description: Imaging Vis/IR radiometer whose characteristics are stressed towards spatial resolution (typically <30 m). Spectral coverage in bands of Vis and NIR (0.4-1.3 Ám). Number of channels can be small (extreme: one, i.e. panchromatic) or very large (hyperspectral) separated in-field (array detectors) or by a spectrometer, or a combination of both. Channel bandwidths from 0.5 Ám (PAN) to 5 nm (hyperspectral). Applicable only in LEO.
