Raman lidar data obtained over a 1 year period has been analysed in relation to aerosol layers in the free troposphere over the Highveld in South Africa. In total , 375 layers were observed above the boundary layer The seasonal behaviour of aerosol layer geometrical characteristics , as well as intensive and extensive optical properties were studied.

In this paper we introduce new in situ observations of atmospheric aerosols, especially chemical composition , physical and optical properties, on the eastern brink of the heavily polluted Highveld area in South Africa. During the observation period between 11 February 2009 and 31 January 2011, the mean particle number concentration (size range 10–840 nm)(More)
