Monitoring Earth's Changing Land Surface
Dec. 3 & 4
The Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) is an imaging instrument that has been operating on NASA's Earth-orbiting Terra satellite since 1999. ASTER is a joint project between Japan, which provides the instrument, and NASA, which provided the platform and the launch. A joint operational team manages and commands the instrument, and a joint science team decides on scheduling priorities and conducts scientific research using ASTER data. The data are being used to answer questions about climate change, look for new mineral deposits, monitor volcanic eruptions, investigate urban heat island effects and numerous other applications. The ASTER project has released a global digital elevation data set that provides the best coverage ever achieved.
