Comparisons of atmosphere density and temperature at heights from 25-60 km measured by a Rayleigh and Na lidar and the occultation technique have been made. The lidar situated in Hochioji Tokyo (35.37 N, 139.23 E) operated routinely, and the occultation data are available at almost the same place and at the same day (Oct.14, 1996), which allows to do these comparisons between different techniques. The limits of these two techniques are discussed respectively. Results show good agreement in density profiles and temperature profiles.
