Lidar visualization of the aerosol stratification and the internal boundary layer in the coastal area in the case of breeze circulation

This paper presents some results of an elastic- backscattering lidar experiment carried out in the Bulgarian Black Sea coastal area in September 1992. The distribution of aerosol within the planetary boundary layer is studied following the variations of the lidar return signals. A combined interpretation of the lidar data with conventionally measured meteorological parameters is made. The obtained results prove the ability of the lidar the cases of sea-to-land and land-to-sea breezes to be distinguished. Based on the changes of the backscattered return signal the prevailing effect of the radiative or advective processes is determined. An attempt is made the height of the thermal internal boundary layer near the shore line to be determined.
