| 摘 要： | 大气校正的精确度主要取决于气溶胶光学特性和漫射透过率等参数的精度.针对目前混浊水域上空气溶胶光学特性反演方法的缺点,给出了基于MODIS图像混浊水域上空气溶胶光学特性反演的新方法,论证了该方法的可行性,并给出了一组通过了验证的用来计算大气漫射透过率的参数.讨论了该技术用于海岸带混浊水域上空大气校正的可行性,可以为我国海洋和风云系列卫星资料的大气校正研究提供相关的技术基础.

| Abstract: | The accuracy of atmospheric correction was decided mainly by the accuracy of aerosol optical characteristics and atmospheric diffuse transmittance parameters. A new algorithm was developed for retrieving aerosol optical characteristics from MODIS images over the turbid waters. The new algorithm of accuracy was also provided. These parameters were used to compute the atmospheric diffuse transmittance. The algorithm was feasible to atmospheric correction of MODIS images for turbid coastal waters. It is useful in studying the atmospheric correction models of HY and FY satellites of China. |
