Combined lidar system for stratospheric and tropospheric ozone measurements

A combined lidar system for the simultaneous measurement of stratospheric and tropospheric ozone concentrations is presented. The lidar was designed at the Physics Instrumentation Center of the General Physics Institute and installed at Kyung Hee University, Suwon, South Korea. To achieve the 3-40 km performance level, two hybrid Raman-excimer lasers and a 60 cm diameter telescope are used. For the stratospheric and tropospheric sounding the 308/353 and 292/319 nm wavelength pairs are applied. We report the description of the system and the results of some preliminary measurements performed in April, May and November 1993 in South Korea.
