Abstract

This paper describes the development of a laboratory prototype unattended LIDAR system to measure aerosol profiles to 10km and ozone profiles to 3km. One consideration in an unattended system is a robust, eye-safe optical design that can provide the necessary signal levels and dynamic range to produce profiles at required height, resolution, and accuracy. An equally important consideration is a set of algorithms to compute aerosol and ozone profiles under a range of atmospheric conditions. NEXLASER employs an atmospheric state model to help identify and adapt to the varied conditions it must encounter. The signal-to-noise requirements of the algorithms are demonstrated and related back to hardware design. Performance of the system is demonstrated with simulated atmospheric conditions.
