The atmospheric boundary layer (ABL) is one of the fundamental part of the atmosphere influencing e.g. air quality, substance transport, etc. In middle latitudes, during radiative weather conditions, it is characterized by typical variability resulting from changes in the radiative balance. Despite the importance of proper parameterization of the boundary layer, particularly in determining the depth of the mixing layer, errors generated by meteorological models can reach up to 100%. Therefore, it is especially crucial to develop an appropriate methodology to fully describe the dynamics of the ABL.

The goal of the measurement experiment is to integrate lidar, sodar, drone, and ground-based measurements to verify assumptions regarding the depth of the mixing height and validate results from atmospheric models. At WOPAS, continuous measurements are conducted using high-power aerosol lidar, monostatic Doppler minisodar, vertical profile measurements with a prototype measurement head installed on a drone, and comprehensive meteorological observations. The integration of multiple measurement methods ensures a robust understanding of ABL dynamics, aiding in the refinement of meteorological models and their outputs, particularly in urban and rural settings
