This paper deals with the development of software that allows one to compute the scattering phase functions of the optical radiation in polydisperse media consisting of spherical particles, based on the Mie scattering theory. The software also enables computer visualization of such optical phenomena as rainbows, glories and coronas. A special technique is used to significantly accelerate the integration over the radius of scattering particles and to increase the calculation rate of the scattering phase functions. Using the software developed, we have performed a detailed analysis of the scattering phase functions for a large number of well-known cloud and fog models, and have created computer images of optical phenomena (rainbows, glories, and coronas) that are inherent to the considered models.
In this paper, we describe numerical and visualization software that allows one to compute phase functions of atmospheric water-drop clouds for an arbitrary distribution of drop radius and represent such optical phenomena as fogbows, glories and coronas. High performance and computational accuracy of the algorithms are provided by the use of a large array of data preliminarily calculated for monodisperse media, and numerical integration by high-order quadrature rules. The software has a user-friendly interface, which allows an interactive design of particle size distributions, simultaneous computation of phase functions for several wavelengths, and immediate visualization of possible optical phenomena.
The paper deals with the simulation of such optical phenomena as halos, glories and coronas. To simulate these, we use the Monte Carlo method taking into account the multiple scattering of solar radiation. We have developed visualization software to represent computational results.
