Cement aerosol plume has been probed by means of a three-wavelength (355, 532, and 1064 nm) and polarization (532 nm) lidar. The depolarization ratio of lidar return from aerosol particles observed outside the visible part of the plume in the area of turbulent pollutant dispersal is near 40%. Characteristic equivalent radius of particles retrieved from lidar measurements of the extinction coefficients is 0.9 ?m. Mass concentration as a function of the distance from the aerosol source is presented. Results on the aerosol mass concentration measured with lidar are in a reasonably good agreement with known published data of numerical modeling and in situ measurements.
