摘要
文章对南黄海(ST03)和珠江口(ST07)海区不同季节的非色素颗粒物吸收光谱数据进行分析,通过分析404个站位的实测数据,得到非色素颗粒物吸收光谱的特点,结果显示两个海区夏季测量的吸收系数在特征波段(440 nm)的吸收值均小于其他季节测量的吸收值。同时,对非色素颗粒物吸收光谱经验斜率进行分析,ST03夏季Sd=0.009 1 nm-1(标准偏差=0.000 8 nm-1),ST03春季Sd=0.009 6 nm-1(标准偏差=0.000 7 nm-1),ST07夏季Sd=0.008 3 nm-1(标准偏差Sd=0.001 8 nm-1),ST07冬季Sd=0.009 7 nm-1(标准偏差=0.000 9 nm-1)。对获取的经验斜率进行验证,评价其在同一海区不同季节的适应性,结果显示经验斜率的应用效果良好。
We measured the absorption properties of de-pigment particles at about 404 stations in South Yellow Sea (ST03)and Zhu Jiang Kou (ST07) of China. ST03 and ST07 cruise absorption at 440 nm is low in summer than in other seasons. The exponential slope of the de-pigment particles absorption spectrum is 0. 0091 nm^-1 (SD= 0. 0008 nm^-1) in summer of ST03 cruise, it is 0. 0096 nm^-1 (SD=0. 0007 nm^-1) in spring of ST03 cruise, it is 0. 0083 nm^-1 (SD=0. 0018 nm^-1) in summer of ST07 cruise and it is 0. 0097 nm^-1 (SD= 0. 0009 nm^-1) in winter of ST07 cruise o The spectral slope is strongly suitable at different seasons in the same sea.
