Mission Objectives:

The ADvanced Earth Observing Satellite 2 (ADEOS-2) Mission is a joint international cooperative program like its successor, ADEOS-1. With a three-year operational life, the mission will support the monitoring of global environmental changes while continuing and furthering the broad-ranging observation technology created by ADEOS-1.

The three scientific goals are:

  • To regularly monitor the water and energy cycle as a part of the global climate system.
  • To quantitatively estimate the biomass and fundamental productivity as part of the carbon cycle, which plays an important role for global warming.
  • To detect the signal of long term climate change as a result of continuous observations succeeded from ADEOS-1.
Mission Instrumentation:

ADEOS-2 has the following instrumentation onboard:

  • Advanced microwave scanning radiometer
  • Global imager
  • Improved limb atmospheric spectrometer
  • Seawinds
  • Polarization and directionality of earth reflectance
  • Retroreflector array
