Biomass burning aerosol play an important role in the Earth’s radiative budget, as it contains a significant amount of black carbon that absorbs solar radiation. The lidar measurements are conducted quasi-continuously over Warsaw at the Remote Sensing Laboratory (RSlab) of the Institute of Geophysics, Faculty of Physics, University of Warsaw since 2013. The measurements performed by the multiwavelength PollyXT lidar system allowed to identify and analyze the cases of biomass burning aerosols inflow over Warsaw from different directions and under different meteorological conditions.
The main identified sources of aerosol from biomass combustion over Warsaw are North America and Eastern Europe (Ukraine), whereas the aerosol from North America was observed in the higher parts of the atmosphere, partly having features of stratospheric smoke. The presentation will report the optical properties based on several selected inflow cases, as well as the unique analysis of the fine-scale aerosol microphysical parameters for the selected case.
