ALOS/AVNIR-2データを使った広島湾南部のクロロフィルa濃度分布推定の初期評価

抄録

The purpose of this research is to study the estimation of surface chlorophyll-a concentrations (Chl-a) using the ALOS/AVNIR-2 data. The southern part of Hiroshima Bay was chosen as a test site. The Chl-a estimation was tried using the AVNIR-2/in-situ Chl-a data set of two days. As a result, a strong negative correlation was observed in the relationship between the AVNIR-2 Band 1 and Chl-a. Moreover, to treat the data at different time with the same data range, the correction of the pointing angle is the most effective. The AVNIR is certified as an effective tool to the Chl-a estimation in the closed gulf such as Hiroshima Bay through this research.
