Abstract
The study of atmospheric aerosol is fundamental in order to get a best comprehension of the atmospheric system and to comprehend how they affect our environment at the local and global levels. Information about aerosol concentration and radiative properties in their ambient environment are indispensable and, in this respect, lidars represent the most powerful tool because their capability to provide information on atmospheric component and parameters with very high spatial and temporal resolutions. Two lidar systems are operational at Istituto di Metodologie per l’Analisi Ambientale of the National Council of Research (IMAA-CNR), Tito Scalo, Potenza, Italy; the first, used in the framework of EARLINET, is able to provide aerosol backscatter coefficient at two wavelengths (355 nm and 532 nm) and extinction coefficient in the UV in the troposphere, and the other, used in the framework of the validation program of ENVISAT, is devoted to measure both tropospheric and stratospheric aerosol in the UV and water vapor up to the tropopause. We present in this paper results obtained starting from three years of systematic aerosol lidar observations and more than one year of water vapor lidar measurements. Both local aerosol and dust transported from the Sahara regions have been characterized.
