We suggest a methodical justification of determining the surface albedo in the near-infrared (NIR) region using the observations of spectral atmospheric transparency and daytime clear-sky radiance in solar almucantar. The contribution of the component describing the reflection processes to radiance at different angular distances from the Sun is analyzed. The effect of aerosol absorption on radiance components used in albedo determination is estimated. The solar zenith angle and elongation of aerosol scattering phase function are found to affect the final result of albedo calculation. © 2016, Pleiades Publishing, Ltd. Source

By using the advanced nano-approach processes and phenomena in self-organizing colloidal systems are studied. The conditions of appearance of self-organized phenomena are determined and also ranges of operation of diffusion, capillary, and fractalization mechanisms are found. © 2013 Sumy State University.

Archival data of measurements of the spectral atmospheric transparency and directional scattering coefficients in southeast Kazakhstan are analyzed. The results of the solution of the radiative transfer equation for the suggested atmospheric radiation model are used to study the diurnal variations of the aerosol optical depth. The data are separated into three basic groups corresponding to the stability of the atmospheric optical parameters, the gradual increase of turbidity with a decrease of the atmospheric mass, and jumplike variations of the aerosol optical depth. The observational data are analyzed taking into account the effects of absorption, multiple scattering, and reflection from the underlying surface. © 2010, Pleiades Publishing, Ltd. Source

The paper describes a method of extracting the aerosol scattering phase function from absolute scattering phase function of brightness, measured in the solar almucantar in the total absence of clouds in the sky. The method is tested on archive observation data, obtained in the semiarid region in southeast Kazakhstan in the visible spectral range. We present the calculations of the directional aerosol scattering coefficients and the corresponding typical aerosol particle size distribution functions. It is shown that these functions are similar to the data from the Solar Village site (Saudi Arabia) of Baseline Surface Radiation Network. © 2011, Pleiades Publishing, Ltd. Source
