基于6S模型的大气透射率改进算法

摘要

6S模型在遥感应用、气候研究等方面具有较高的应用价值。为了解决6S模型中大气透射率计算精度较差的问题，利用最小二乘法，结合温度与气压对6S大气透射率计算法进行改进。实验表明，改进模型不但能提升大气透射率计算精度和稳定性，而且适用于不同大气模式。%6S model has been widely applied in remote sensing,climate research and other fields.In order to solve the problem of poor accuracy of atmospheric transmittance in 6S model,a modified model was proposed combining temperature and pressure with LS method.The results show that the modified model not only improve the accuracy and stability of the atmospheric transmittance,but also is suitable for different atmospheric models and molecules.
