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
ATLAS
Advanced Topographic Laser Altimeter System
Operational
Provide date on ice sheet height and sea ice thickness, land altitude, aerosol height distributions, cloud height and boundary layer height.Lidar altimeter
AVHRR/3
Advanced Very High Resolution Radiometer/3
Operational
Measurements of land and sea surface temperature, cloud cover, snow and ice cover, soil moisture and vegetation indices. Data also used for volcanic eruption monitoring.n/a
