Lidar mefsurements of tropospheric aerosol in the frameworks of LRMC - 2017

Nighttime sessions, based on the data of multifrequency sensing in Tomsk, make it possible to separate vertical layers with different scattering / absorbing properties and to estimate aerosol characteristics. Optical parameters – the lidar ratio and the Ångström exponent – are associated with aerosol advection at different altitudes of the troposphere. It is shown that the average radius of small particles and their contribution to the total concentration of particles are also combined with the backward trajectories of the air mass motion. The advection of air weaker affects the complex refractive index, especially its imaginary part.
