The development of a lidar system for measuring near simultanously size distribution, aerosol extinction, and turbulence profiles up to 20 kn altitude was reported. The atmospheric aerosol contributions to laser beam widening for a horizontal propagation path at various elevations was estimated on the basis of measurements and a Monte Carlo beam propagation model. This was compared with the beam widening caused by turbulence. Results showed that the beam widening caused by the aerosols was very significant.
