激光通信是水下无线通信的新热点,准确评估海水中激光的传输衰减是信道研究的关键。综合现有的QAA-RGR(Quasi-Analytical Algorithm Red-Green-bands-Ratio)遥感反演算法和国家卫星海洋应用服务(NSOAS)模型,提出了一种新的遥感反演算法,可直接通过中分辨率成像光谱仪(MODIS)遥感数据反演得到海水衰减系数光谱。结合MODIS模型提供的L2级数据,对比反演所得的吸收系数光谱和散射系数光谱,验证了反演算法的可行性。该反演算法对动态分析和把握我国沿海地区的海水光学特性具有重要意义。
Laser communication is a new hot spot in underwater wireless communication. Accurate assessment of laser transmission attenuation in seawater is the key of channel research. Based on the existing Quasi-Analytical Algorithm Red-Green-bands-Ratio remote sensing inversion algorithm and National Satellite Ocean Applications Service (NSOAS) model, a new remote sensing inversion algorithm is proposed, which can directly pass through The seawater attenuation coefficient spectrum was obtained by using MODIS remote sensing data. Combined with the L2 data provided by MODIS model, the inversion of the absorption coefficient spectrum and the scattering coefficient spectrum is verified, and the feasibility of the inversion algorithm is verified. The inversion algorithm is of great significance for the dynamic analysis and grasping of seawater optical properties in coastal areas of China.

由于人类活动的加剧,温室气体排放量的增加,全球气候正在变暖。据专家分析20世纪全球平均气温已经上升了0.74℃,并预计到2100年将上升1.8-4.0℃。我国未来20-100年地表气温也将明显升高,预计到2020年全国平均气温将较1961-1990年的平均气温增加1.3-2.1℃,到2050年将增加1.5-2.8℃。有关气候变暖对我国粮食生产影响的报道较多,但这些研究多基于模型预测和历史资料分析得
