Abstract

The vertical distribution of tropospheric ozone was measured by a two-wavelength differential absorption lidar based on excimer lasers. Emission of a XeCl laser (308 nm) and stimulated Raman scattering of methane (290.4 nm) pumped by a KrF laser were used. Ozone concentrations in an altitude range of 4–12 km were determined with a resolution of 750 m. The proposed method can be used to measure the ozone distribution over a wide altitude range (2–28 km) with high reliability because the excimer–Raman hybrid laser is simple and has high average power and a high repetition rate, in comparison with frequency-doubled two-wavelength dye lasers.
