Abstract
During Dynamics Adapted Network for the Atmosphere from January 1990 through March 1990, 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.
