The Stratospheric Ozone Monitoring Radiometer (SOMORA) is continuously operated in Switzerland and measures ozone volume mixing ratio 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 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 series of lower mesospheric ozone. Oscillations with periods of 5–30 days are present in the S and series.
