| 摘 要： | The sky radiance and degree of polarization with multiple scattering process considered were calculated inthis paper by solving vector form radiative transfer equation iteratively. Numerical experiment for simultaneouslyretriving the size distribution (SD) and the complex refractive index (CRI) of aerosol particle was conductedwith the degree of polarization of skylight (DPS) and the library method used. It is shown from the resultsthat the real part of CRI is always sensitive to DPS. But situation is somewhat complicated for the imaginarypart of CRI. Therefore, it is expected that the real part of CRI can be retrieved from DPS and its imaginarypart should be retrieved as the particle is large in size. In this paper, seven sets of DPS measurements on 6 January,1990 in Beijing were given and the optical characteristics of aerosol were retrieved.

| Abstract: | The sky radiance and degree of polarization with multiple scattering process considered were calculated in this paper by solving vector form radiative transfer equation iteratively. Numerical experiment for simultaneously retriving the size distribution (SD) and the complex refractive index (CRI) of aerosol particle was conducted with the degree of polarization of skylight (DPS) and the library method used. It is shown from the results that the real part of CRI is always sensitive to DPS. But situation is somewhat complicated for the imaginary part of CRI. Therefore, it is expected that the real part of CRI can be retrieved from DPS and its imaginary part should be retrieved as the particle is large in size. In this paper, seven sets of DPS measurements on 6 January, 1990 in Beijing were given and the optical characteristics of aerosol were retrieved. |
