Lidar measurement of the aerosol extinction profile in Black Sea coastal zone

The paper presents a lidar study of the volume extinction coefficient in the atmosphere at the Bulgarian Black Sea coast in the presence of a breeze circulation. An attempt is made to evaluate the influence of the meteorological parameters on the optical properties of aerosol. In the case of a land-to-sea breeze and a layered structure of the atmosphere (stable stratification), the height of the thermal internal boundary layer formed over the sea surface is compared with analytical models. In the case of an atmospheric convective boundary layer, an increase in the aerosol extinction with height is observed. The results are compared with an analytical model of the aerosol extinction profile in a well-mixed marine boundary layer. In both cases, the experimental results are in a good agreement with the analytical models.
