In the paper we present the results of computational experiments aimed to define the angular distributions for the polarized radiation scattered in a cloudy layer. The angular distributions for Stokes parameters were computed by Monte Carlo method fo

Scattering matrices for horizontally oriented ice crystals are calculated with a code based on the geometric optics. The main physical regularities inherent to the scattering matrices are discussed. Degree of polarization of the scattered light is sh

Pure rotational Raman scattering signals from atmospheric gases such as nitrogen and oxygen can be used to deduce the temperature of the atmosphere. Previously, this method has been successfully implemented as a remote temperature sensing lidar syste

Worldwide nearly 150 million people are suffering from diabetes mellitus: approximately 90 to 95 % of them, i.e. 135 to 142 million are type-2 diabetic patients exhibiting the most important endogenous cardiovascular risk condition. The development o

Backscattering of light by hexagonal ice columns and plates has been calculated by means of a ray-tracing code. It is shown that backscattering by the hexagonal ice cylinders at their arbitrary orientations is caused by a peculiar corner-reflector ef

In this paper we study the light scattering in water-drop clouds for various distributions of droplet size. Polarization and angular distributions are simulated by Monte Carlo method for radiation reflected by cloud layers. Computational results make

We transform a compartmental model given by a set of deterministic differential equations and a set of discrete system parameters into a system of stochastic differential equations and obtain a mixed graphical model by time discretization. This mixed

To model fields of broken clouds, we consider two methods based on Gaussian random fields and one method based on truncated random paraboloids. These models are determined by a few parameters only: the amount of cloud, the mean cloud base diameter an

By Monte Carlo simulation we investigate the two effects as a result of the specific radiation regime of the cloudy atmosphere caused by multiple light reflection between the clouds and the surface: the increase of solar radiation intensity near the
