摘要：
Aiming at the complex atmosphere environment on Mars, using the T-matrix theory, the scattering characteristics of three kinds of Mars dust particles with non-spherical shape were studied. Then the scattering characteristics of non-spherical Mars dust particles with lognormal distribution were calculated, and under the conditions of sandstorm and no sandstorm, the variation trend of attenuation coefficient and transmittance of non-spherical Mars dust particles with particle number concentration, wavelength and height was analyzed, and compared with spherical particles.The results show that the extinction efficiency factor and scattering efficiency factor of non-spherical and spherical particles are quite different, and the difference between them is as large as 1.786 8 and 1.761 9. The scattering characteristic of chebyshev particles is the closest to that of spherical particles. When the incident wavelength is 0.55 μm, the overall scattering of dust particle swarm on Mars is mainly concentrated within 40° forward direction, and the scattering intensity of non-spherical and spherical particles are basically equal within 60° forward direction. When the scattering intensity is larger than 60°, the non-spherical particles have higher scattering intensity than spherical particles. The attenuation coefficient and transmission of non-spherical Mars dust particles (with wavelength, particle concentration, and height) are basically consistent with the spherical particles, and when the size ratio is closer to 1, its attenuation coefficient and transmission coefficient are closer to the value of spherical particles. © 2019, Science Press.
