– Data of remote multiangle measurements of reflected radiance are used for retrieval of the optical thickness, single scattering albedo and phase function parameter of cloudy and clear atmosphere. The method of perceptron neural network allows obtaining the surface albedo, optical thickness, single scattering albedo and phase function parameter from input… (More)
The Cauchy problem for the equation u (t) = Au(t) + BW(t) , t ≥ 0, with white noise W and A being the generator of regularized semigroups is studied in different spaces of distributions. Solutions of the problem in spaces of distributions with respect to time variable, random variable and both time and random variables are studied.
– Studies of the UV-radiation are the most actual ecological problems that are called by ozone depletion increasing the level of biologically active solar UV-B radiation in the biosphere. The air pollution and atmospheric aerosols prevent penetrating appropriate dose UV radiation, which is beneficial for people, specifically due to production of vitamin D 3… (More)
Simple analytical methods are proposed for calculating the reflection function of a semi-infinite and conservative scattered layer, the value of which is needed to solve many atmospheric optics problems. The methods are based on approximations of the exact values obtained with a strict numerical method. For a Henyey-Greenstein phase function, knowledge of… (More)
