ADEOS is the Advanced Earth Observing Satellite, developed by NASDA (the National Space Development Agency of Japan). The instrument was designed to operate for 3 years. The satellite flew in a 800km orbit, giving full daily global coverage, and used the following wavebands: 308.6, 312.5, 317.5, 332.2, 331.2, 360.0 nm. On June 30, 1997, the ADEOS Spacecraft failed and was replaced by EarthProbe/TOMS",
