The paper presents the results of tropospheric aerosol studies in different regions of the Arctic. The data have been obtained on the spatial distribution of the Arctic haze in north regions of Russia, Atlantic, and Canada. The haze was investigated by means of a lidar placed onboard the "Tsiklon" IL-18 aircraft-laboratory. The paper gives the data on the vertical and horizontal distributions of the scattering coefficient that characterizes the optical density of the tropospheric aerosol, including the Arctic haze. It has been found that the values of the arctic haze scattering coefficient differ insignificantly in different regions of the Arctic. However, in summer the values of this characteristic without haze are 2-3 times less than those with haze in the same region.
