Quantifying Vertical Concentration of Long-Range Transported Biomass Burning Aerosols from Canadian Wildfire in 2023 Using Lidar Observations

During the unusually long wildfire season in 2023, the multi-wavelength Mie-Raman-polarization-fluorescence lidar recorded a long time series of transported biomass burning aerosols. With these observations, we obtained a comprehensive dataset about the optical and microphysical properties of BBAs. In this study, we present a method for estimating BBA volume/mass concentrations from lidar observation. The derived profiles of volume and mass concentration show good consistency with airborne measurements and model simulations, respectively.
