Multichannel Earth observation data have been available to the science community since the launch of ADEOS. To retrieve several geophysical parameters, not one, we need multiple-band observation. The ADEOS satellite carried eight instruments that covered bands from ultraviolet to microwave. We have begun to analyze the spectrally wide ADEOs data, or multiple- instrument data, to seek new methods to infer crucial geophysical parameters. Satellites observed data in the visible and near infrared bands comprise radiation from molecular scattering (Rayleigh scattering), aerosol scattering (Mie scattering), water vapor absorption, and surface reflection. The separation of components is an important goal of satellite remote sensing retrieval. In this paper, we introduce the ADEOS satellite, its instrumentation, and the ADEOS SYNERGISM dataset. We will discuss the characteristics of the radiance received by satellites and show interesting data and properties derived from the ADEOS SYNERGISM dataset. We will also discuss further separation of the components that constitute satellite observed data in the visible and near- infrared bands.
