"本研究將利用多重衛星資料，及衛星多波段的特性，先將衛星所觀測到的輻射強度及遙測反射率，先辨識區分為近陸地海域(inner region)、陸棚海域(middle region)、及大洋海域(outer region)。再依衛星多波段在不同海域的特徵，蒐集現場葉綠素歷年觀測資料，並配合研究船的每季航次，以輻射光譜儀現場觀測海面輻射強度與反射率觀測資料，同時採水量測葉綠素濃度。以建立鄰近陸地的二類水體及遠離陸地影響的一類水體等不同海域上的葉綠素濃度演算法，以期建立西北太平洋的邊緣海域上更接近現場實測值的衛星資料葉綠素濃度演算法，提供海洋生地化及海洋與大氣交互作用等研究應用。進而分析葉綠素甲濃度的時間與空間的分布，探討其受氣膠、風等大氣因素及海溫、渦流等海洋因子的影響。""The multi-satellite data and satellite multi-band data will be used in this study. The multi-band radiance and remote sensing reflectance will be used to distinguish the ocean into the inner region, the middle region, and the offshore region. The sea surface radiant intensity and reflectance will be measured by radiation spectrometer on the ocean research cruises in each season. The water of different regions will be sampled to measure the chlorophyll-a concentration on the cruises, too. The in-situ chlorophyll-a concentration data over the years will also be collected in this study, and the satellite multi-band characteristics on different water regions are considered. Meanwhile, the more accuracy chlorophyll-a concentration algorithms will be established for the adjacent land Case 2 water and the offshore region Case 1 water for the marginal sea of north western Pacific. In addition, the algorithm result can be applied to the marine geobiochemical research and ocean–atmosphere interaction research. Moreover, the spatial and temporal distribution of chlorophyll-a concentration could be analyzed precisely."
