Abstract
A comparative analysis of the characteristics of the aerosol obtained in the Caspian Sea on the RV "Rift" in November 2008 and in October 2012, in the near-water atmospheric layer and throughout the entire thickness of the atmosphere. Under study were: aerosol optical depth (AOD in the wavelength range 0.3–2.14 microns) and the columnar water vapor of the atmosphere, particle number concentration and particle size distribution in the range of 0.3–20 microns in diameter, the mass concentration of submicron aerosol mass concentration and absorbing aerosol – "soot", chemical ionic composition of the soluble part of aerosols and trace gases – Cl–, SO42–, NO3–, РО43–, F–, HCO3–, Na+, NH4+, K+, Mg2+, Ca2+, H+, HCl, HNO3, SO2, NH3.
