Abstract

Based on the size distribution function and concentrations of aerosol particles which were determined in the coastal zones of the southern Baltic Sea by means of the lidar method the aerosol concentrations and their gradients above the sea surface were derived. The measurements were carried out under various meteorological conditions and in various seasons of the year taking into consideration such factors as wind direction, duration and velocity and different types of sea bottoms. It was confirmed that aerosol concentrations and their gradients were relatively high in fall and winter when the winds blew from the shore. Coal burning heat production for city inhabitants during the colder months influences this phenomenon, since there is a substantial amount of pollution produced which is carried with the winds over the sea in the form of aerosols. For the winds from the open sea directions the values of concentrations and gradients were substantially lower even though the wind velocity was much greater.
