东中国海水体悬浮颗粒物的光谱吸收特征研究
|
摘要
深入了解水体光谱吸收特征,对于建立水色遥感光学模型,提高水色遥感的定量反演精度具有重要作用。本文结合2016年9月以及12月两班航次的实测数据,计算并比较东中国海三个海域的悬浮颗粒物的吸收系数、比吸收系数,再结合叶绿素a浓度及总悬浮颗粒物浓度对吸收特征进行分析。分析结果表明,总悬浮颗粒物的光谱吸收特性、比吸收特性均与浮游藻类颗粒物的类似,其在波段440nm和675nm有明显的吸收峰,非藻类颗粒物吸收系数随波长增加而不断减小;从整体上来看,渤海的吸收系数最大,黄海次之,东海最小。
Spectral absorption characteristics of water plays an important role in establishing an optical remote sensing of ocean color model and improving the accuracy of water color remote sensing quantitative inversion. Based on the measured data of two voyages in September 2016 and December, the absorption coefficient and specific absorption coefficient of suspended particles in the three sea areas of the East China Sea were calculated and compared, and the absorption characteristics were analyzed with the concentration of chlorophyll a and the concentration of total suspended particles. The results show that the spectral absorption and specific absorption properties of the total suspended particles are similar to those of the planktonic algae particles. The absorption peaks of the particles in the band 440 nm and675 nm are obvious, and the absorption coefficient of nonalgal particles decreases with the increase of the wavelength.On the whole, the absorption coefficient of Bohai Sea is the largest, followed by the Yellow Sea, and the East China Sea is the smallest.
