Lidar Measurements of Ozone and Temperature in the Stratosphere at Tsukuba(36.1.DEG.N,140.1.DEG.E) during DYANA Campaign.

the vertical profiles of stratospheric ozone and temperature were obtained by a Meteorological Research Institute Mark II mobile lidar.The ozone concentrations in an altitude range of 21-24km were low at Tsukuba in February 1990.The temperature profile on 17 February 1990 showed a flat structure from-43km to-60km near the stratopause.The temperature from 35km to 45km gradually decreased during 6 March through 20 March 1990.middle atmosphere dynamics.It was performed in January through March 1990 in the northern hemisphere (OFFERMAN,1991).The preliminary data of ground based and rocket observations carried out in Japan were summarized by OYAMA (1991).We present in this paper observational results obtained by the Meteorological Research Institute (MRI) Mark II mobile lidar which was developed for simultaneous measurements of ozone, temperature and aerosols in the stratosphere (UCHIN0 and TABATA, 1991).
