Paper Abstract

In this paper the possible synergy between advanced lidars and ceilometers for the monitoring of atmospheric aerosols is evaluated. The advanced measurement capabilities of the multi-wavelength Raman lidar are used to investigate the capability of ceilometers to provide reliable information about the atmospheric aerosol content. At the CNR-IMAA Atmospheric Observatory (CIAO), a ceilometer is operational since September 2009 providing vertical profiles of atmospheric backscatter at 1064nm up to 15km; at the same location, the Potenza EArlinet Raman Lidar (PEARL), a quality-assured, multi-wavelength Raman lidar operates in the framework of EARLINET and performs regular measurements plus measurements of special events (Sahara dust outbreaks, volcanic eruptions etc.). Using the PEARL data products as a reference, the capability of ceilometers to detect aerosol layers and provide quantitative information about the atmospheric aerosol load is investigated. The variation of ceilometers' performance in different atmospheric conditions is analysed. A procedure for obtaining backscatter coefficient profiles from ceilometer signals is proposed and its limitations are discussed.
