Advanced Space borne Thermal Emission and Reflection Radiometer (ASTER) is a high resolution remote sensing instrument associated with which of the following satellite:

ATerra

BLandsat

CSPOT

DSentinel

Answer:

A. Terra

Read Explanation:

  • The Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) is a high-resolution remote sensing instrument onboard NASA's Terra satellite, launched in 1999.

ASTER provides high-resolution imagery of the Earth's surface in 14 spectral bands, including:

  • Visible and near-infrared (VNIR)

  • Short-wave infrared (SWIR)

  • Thermal infrared (TIR)

ASTER's key features:

  • Spatial resolution: 15-90 meters (depending on the band)

  • Swath width: 60 km

  • Revisit time: 16 days

Applications:

  • Land surface temperature mapping

  • Mineral identification

  • Vegetation monitoring

  • Soil moisture estimation

  • Disaster monitoring (e.g., wildfires, floods)
