Aerosol scattering phase function for the arid territory of southeast Kazakhstan

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.
