The Stratospheric Ozone Monitoring Radiometer (SOMORA) is continuously operated in Switzerland and measures ozone volume mixing ratio qo3 in the stratosphere and lower mesosphere with a time resolution of about 30 min. Temporal variances S (wave period band 1-3 h) of daytime and nighttime ozone are studied at an altitude of 55 km from October 1, 2000 to May 1, 2001. Gravity waves are assumed as cause of the observed short-time fluctuations of qo3. Strong negative and positive correlations are found between the dynamic state of the stratosphere (represented by time series of ERA-40 reanalyses) and SOMORA's S and qo3 series of lower mesospheric ozone. Oscillations with periods of 5-30 days are present in the S and qo3 series.
