# ASTER (Advanced Spaceborne Thermal Emission and Reflection Radiometer)
*sensor . products*

Three-telescope multispectral imaging radiometer aboard Terra (EOS AM-1), jointly developed by METI/Japan and NASA, covering 14 bands from visible through thermal infrared (520-11650 nm). VNIR 15 m, SWIR 30 m (non-operational since approximately April 2008), TIR 90 m, 60 km swath. The pre-2008 SWIR archive (bands 4-9, 1.60-2.43 um, with bands 6-9 at 2.145-2.43 um particularly diagnostic for clay, carbonate, and sulphate alteration mineral identification) is the foundational global dataset for regional lithological and mineral alteration mapping.
