EXCIMER-LASER-BASED LIDAR SYSTEM FOR STRA TOSPHERIC AND TROPOSPHERIC OZONE MEASUREMENTS

A differential-absorption lidar system was devel-oped on the basis of electric-discharge excimer lasers. It was designed to measure the ozon e concentrations in the atmosphere at altitudes of 3 - 32 km. The radi ation from an Xe - Cl laser and the first Stokes component, resulting form the scattering of this radiation in hydrogen (308 and 353 nm), we re used in the stratospheric measurements. The second and third compon ents of the radiation from a Kr - F laser scattered in deuterium (292 and 319 nm) were used in the troposphere. The system was tested in the city of Suwon in South Korea. The results of the stratospheric ozone measure-ments carried out there in April and May of 1993 were in good agreement with the average data obtained by satellite (Nimbus-7) monit oring of the subtropical region.
