Simultaneous surface-based remote sensing with optical (Ceilometer) and acoustic (Sodar) methods allows the diurnal variation of the structure of the atmospheric boundary layer to be deduced with high temporal resolution. Primarily the convective boundary layer, the nocturnal stable surface layer, and the residual layer can be identified from the measured vertical profiles of aerosol concentration and thermal fluctuations. The ability of the two remote sensing techniques is shown in different examples from two different locations and two seasons. The impact on urban air quality assessment is addressed.
