The atmospheric boundary layer (ABL) is the part of the troposphere directly influenced by the properties of the Earth’s surface. The ABL thickness reaches from hundreds of meters to a few kilometres. The daily cycle of the ABL height is primarily result of interaction between incoming solar radiation and Earth’s surface heat fluxes because a turbulent motion is dominant in this layer. Air pollutants are generally emitted from surface and their measured concentrations are also influenced by dilution of the atmosphere, or ABL thickness. This study is focused on the linkage between the diurnal ABL height evolution and aerosol particle number concentrations.
