Abstract
A KrF‐laser‐based ozonelidar system is described which operates in the wide vertical range between 0.1 and 12 km. The wavelengths used for the measurements are generated by efficient stimulated Raman scattering which is optimized by using a KrF laser in an oscillator‐amplifier configuration. Two receiving telescopes are used to divide the considerable dynamic range of the backscattered signal which covers more than eight orders of magnitude. The ozone density errors are smaller than 7.5×1016 m−3 (i.e., 3.1 ppbv near the ground) which is comparable to those of standard ozone monitors. A further improved performance is expected in the future. A first annual series with about 580 individual measurements was carried out in 1991 and is briefly discussed.
