Aerosol extinction profile over the river Volga along the path Moscow-Nizniy Novgorod-Moscow

摘要

The experimental data of the backscatter coefficient profile and aerosol pollution over the river Volga along the path Moscow to Nizniy/Novgorod to Moscow obtained with the eye-safe backscatter compact lidar during the complex ecological expedition on board the ship `Ilia Repin' 28 June to 7 July 1993 are presented. We detected the visible and invisible aerosols layers and smoke plume over industrial and ship chimneys. The data obtained in similar conditions allowed us to find pollution-free regions. These regions, such as the village Ples, are considered as a base or background for an aerosol pollution degree estimation within industrial centers and over the Plesheevo Lake near the Russian-USA ecological station.
