According to the retrieval theory, the forward problem is the modeling of the real atmos -phere . All physical inverse problems start from forward problem . However, the accuracy of forward radiances depends upon the first guess and precision of channel transmittances. Therefore, the retrieval procedure relates with first guess, as well as forward problem and transmittances closely. In addition to set up a consistent simultaneous retrieval model this study, especially compare the ISPRM with the SPRM which changes...

According to the retrieval theory, the forward problem is the modeling of the real atmos -phere . All physical inverse problems start from forward problem . However, the accuracy of forward radiances depends upon the first guess and precision of channel transmittances. Therefore, the retrieval procedure relates with first guess, as well as forward problem and transmittances closely. In addition to set up a consistent simultaneous retrieval model this study, especially compare the ISPRM with the SPRM which changes only a priori information parameter, and thus call ISPRM . It is shown that the result of ISPRM is much better than the SPRM 's .

从反演理论知道,正演问题是对实际大气辐射率的模拟.一切物理反演皆始于正演,而正演辐射率的逼真度又取决于初估值和遥感通道透射率的精度,从而反演过程紧密地把初估值、正演和透射率联在一起.这个研究除了构建自洽的同步反演模式外,着重将SPRM和只改变验前信息参数的SPRM做综合比较,并称后者为ISPRM.试验结果表明后者明显优于前者.

By field experiment in water sampling for chemical analysis and synchronous measurement of reflected light spectrum of water, the optimal channel combination models were obtained to retrieve chlorophyll-a concentration and suspended sediment concentration from remote sensing data of FY-1C multi-channel scanning radiometer, Landsat-5 TM, SeaWiFS of Seasat and a supposed set of remote sensing channels. A method retrieving water quality parameters by satellite remote sensing was suggested, in which the atmospheric transmittance and reflectance were determined by the reflected light spectrum of standard reflecting board on water and satellite remote sensing images themselves for the atmospheric calibration. The models and methods were used to retrieve the eutrophic degree, its space distribution and its change with year of Tai lake and Dianchi lake, which are typical eutrophic lakes of china, in 1980s and 1990s. The results of this study could be as the bases for operational satellite remote sensing of water quality of lake.

通过系统性的常规水质采样分析与水面光谱测量外场同步试验,建立了由FY1C多通道扫描辐射计、Landsat卫星TM和Seastar卫星SeaWiFS等在轨卫星多通道遥感器以及一组设想的遥感通道遥感反演叶绿素a浓度和总悬浮物浓度的优化通道组合模型,提出了一种利用水面上标准反射板的反射光谱和遥感图像本身确定大气透过率和反射率从而实现大气校正的水质指标卫星遥感反演方法.所建立的模型和方法被用于遥感解译我国典型富营养化湖泊太湖和滇池从80至90年代的富营养化程度及其分布状况随年份的变化.本项研究为进一步开展湖泊水质业务化卫星监测打下了基础.
