The Tikhonov Regularization Method Improved by Genetic Algorithm is used to Retrieve the Non-Spherical Particle Spectral Distribution

Abstract

In this paper, an improved Tikhonov regularization method based on genetic algorithm is proposed to retrieve the non-spherical aerosol particle spectral distribution. Based on the ellipsoid and the cylindrical shape aerosol particles, for example, the T matrix method is used to get the ball, aerosol optical parameters using genetic algorithm combining with Tikhonv regularization method, fitting the same refractive index under the environment of different forms of spherical particle distribution, after analyzed the optical parametric data for the influence of particle distribution in inversion algorithm. The experiments show that the Tikhonov regularization method based on the improved genetic algorithm proposed in this paper is an effective method to retrieve the non-spherical aerosol particle spectral distribution, and the inversion effect is better.
