[abstract] We present the results of the aerosol measurements carried out over the Aegean sea during the Photochemical Activity and solar Ultraviolet Radiation campaign held in Greece during June 1996. Simultaneous observations performed with a lidar and a double-monochromator spectrophotometer allowed us to retrieve the optical depth, the Angstrom coefficient, and the backscatter-to-extinction ratio. The sun-photometric data can be used to improve quantitative aerosol measurements by lidar in the Planetary Boundary Layer. Systematic errors could otherwise arise, because the value of the backscatter-to-extinction ratio has to be supplied. Instead, this ratio can be retrieved experimentally by using an iterative solution of the lidar equation.
