System verification of an unattended DIAL lidar

A laboratory prototype of the NEXLASER unattended aerosol and ozone LIDAR was operated in the Atlanta metropolitan area during the ozone season of 2002. An important aspect of an unattended LIDAR system is the ability to automatically assess system problems and correct for them. This paper details the set of tests that have been conducted to verify system performance, discusses how the tests have been incorporated into NEXLASER's operational software, and shows how aerosol and ozone data collected by the system compares to other measurements.
