Abstract
The adjacency effect is discussed at coastal areas of main land and peninsula using VNIR and SWIR on ASTER sensor, although the cross-talk phenomenon is apparently noted on some SWIR. The purpose of the analysis is to derive optical characteristics of atmospheric aerosol. The aerosol model is in accordance to the dust-like model. This model is adopted to ASTER and MISR on Terra satellite. Data is the Atsumi Peninsula near Nagoya (34° 40'N, 134° 00'E) GMT1.55 on July 10,2000. The ASTER SWIR(1.65μm-2.395μm) cross-talk phenomenon is noted in the data. This is known as a result of a structure of ASTER sensor. It is relatively large (5-6 DN counts and 100 lines or 3km length). On the other hands, when ASTER observe heterogeneous surface of coastal water, the adjacency effect due to the scattering by atmosphere might partly be contaminated to the above effect. In the SWIR region of spectrum, molecular scattering is practically neglected. However, some aerosol model indicates strong scattering effect at SWIR wavelengths. The main results are (1) The Japan Main land indicates 6~20 times more effect than the peninsula on adjacent radiance from ocean water. (2) SWIR & VNIR exhibit similar adjacent effect which might indicate aerosol or large particles.
