[Abstract]

　Data obtained with an ozone lidar at the National Institute for Environmental Studies(NIES) were estimated and analyzed. Methods to check the systematic errors were carefully examined. Comparison with the data observed with the satellite sensor SAGE II was carried out to confirm the accuracy and good agreements were obtained. Thus, vertical profiles of ozone from 15km to 45km have been archived. Temperature profiles from 30km to 80km can be also obtained from the off-resonant signal of the ozone lidar which could give information on dynamical; motions in middle atmosphere and effects of ozone depletion and global warming. Seasonal variations of ozone were different with altitude. A method to correct the effects of the Pinatubo aerosols on the ozone lidar measurements were discussed.
