Mobile lidar for simultaneous measurements of ozone, aerosols, and temperature in the stratosphere

Abstract

A Meteorological Research Institute Mark II mobile lidar was developed for simultaneous measurements of ozone, temperature, and aerosols in the stratosphere. The lidar consists of an XeCl laser, a Nd:YAG laser, and an 80-cm diam receiving telescope. The laser beams at three wavelengths (308, 355, and 532 nm) can be almost simultaneously transmitted. The purpose of this lidar is to study, for example, the aerosol impact on the ozone layer through radiative and photochemical processes, the aerosol impact on the Umkehr measurements after violent volcanic eruptions, and the interaction between temperature and ozone. The performance of the lidar system and some data about ozone, aerosols, and temperature are described.
