Abstract

We had been conducting the results of surface spectroscopy of radiometric measurements of aerosol and water vapor in the atmosphere of Volgograd for period since July 2011 for September 2013, applying a SPM photometer. Volgograd is a city in the southeast of the European part of Russia, the administrative center of the Volgograd region. It's located in latitude 48.42 N, longitude 44.28 Е and altitude 156 meters above sea level. Spectral aerosol optical depth, the Angstrom wavelength exponent and general water vapor content were computed with the help of the data having been written on sun photometer through the direct measuring of sun radiance. The mean values of aerosol optical depth at 0.440 μm, water vapor the atmospheric column and the Angstrom wavelength exponent during the indicated period of time were computed to be 0.20 ± 0.12, 1.97 ±0.67 g/cm² and 1.58 ± 0.71 accordingly. The maximal and minimal values of aerosol optical depth were recorded in August 2013 and in July 2013. The general water vapor content in the vertical atmospheric column was recorded in August 2013 and in November 2012). Using the method of the least squares the Angstrom exponent in the spectral measurements from 0.440 to 0.870 μm was computed.
