ASTERの大気補正処理,大気への応用

抄録

To derive the earth surface (Ocean) parameters efficiently, a contamination of the atmospheric constituents is to be investigated, since their contribution to the satellite data would be about 80-90% in the visible region over the ocean. Thus it is our purpose to present efficient atmospheric correction algorithms to derive parameters involved in ASTER sensor ranging from visible to infrared windows by setting up an appropriate numerical model. A schedule of algorithm development discussed at the US-Japan ASTER team meeting which was held in May, 1994 is shown. Cloud screening, turbid atmosphere, and adjacency effect are main targets for the use of such sophisticated sensor as ASTER.
