First result of photometric measurements aerosol optical thickness and total water vapor content over the territory of Volgograd

Measurements of aerosol optical thickness (AOT) and water vapor content in Volgograd. Evaluated average daily and monthly mean aerosol optical properties. Comparisons with satellite observations were conducted. It is shown that calibration of the photometer in Western Siberia could lead to systematic errors in the recovery of the absorbing mass of H2O in the Lower Volga.
