Instrument | Status/ Accuracy | Instrument Description | Measurement Technology | Timeline |
ASTER Advanced Spaceborne Thermal Emission and Reflection Radiometer | Operational
| 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. | n/a | |
