Mission Objectives:

The ADvanced Earth Observing Satellite 1 (ADEOS-1) "MIDORI" , launched in August 1996, was the first in a series of two scheduled joint international cooperative programs to contribute to global environmental monitoring. The objective of ADEOS-1 was to acquire data on worldwide environmental changes such as the greenhouse effect, ozone layer depletion, tropical rain deforestation, and abnormal climatic conditions. A secondary objective was to develop platform bus technology, interorbital data relay technology, etc. which are necessary for the development of future earth observation systems.

Mission Instrumentation:

ADEOS-1 had the following instrumentation onboard:

  • Advanced visible near infrared radiometer
  • Ocean color and temperature scanner
  • Scattering measurement device
  • Total ozone mapping spectrometer
  • Polarization and directionality of the earth's reflectance
  • Interferometric monitor for greenhouse gases
  • Improved limb atmospheric spectrometer
  • Retroreflector In-Space (RIS)
