OVERVIEW OF ADEOS
The Advanced Earth Observing Satellite (ADEOS), also known as the
Earth Observation Platform Technology Satellite “Midori” in Japan, was
launched on 17 August 1996. It stopped operating on 30 June 1997 after an
operational phase of about eight months, due to a malfunction of its flexible
solar paddle. The mission of ADEOS is to obtain global Earth Observation
data using eight onboard sensors to contribute to the international
cooperative monitoring of the global change, such as the global warming, the
atmospheric ozone depletion over the Antarctic and the Arctic circles, the
decrease of tropical rain forest, the abnormal weather and so on.
This space mission is addressing a number of global issues and will prove
useful in a variety of practical and operational applications, including
the frequent observation of the sea surface temperature and ocean color
(an indicator of the chlorophyll-a concentration) by the Ocean Color and
Temperature Scanner (OCTS),
the improvement of weather forecast accuracy using NASA’s
Scatterometer (NSCAT),
the continuous monitoring of global total ozone content in the
atmosphere with the Total Ozone Mapping Spectrometer (TOMS),
land use and land cover classification, the generation of digital elevation
models, and the observation of disaster areas using the Advanced Visible
and Near-Infrared Radiometer (AVNIR).
