Ozone profiles contain narrow layers of substantially enhanced or reduced ozone, called positive and negative laminae, respectively. They reflect both evolutions of stratospheric ozone content and stratospheric dynamics. Here we deal only with positive laminae. The following lamina characteristics are investigated in dependence on lamina size: the number of laminae per profile, the overall ozone amount in laminae per profile and the ozone amount in one lamina at the European ozonosonde stations. An important role of the vertical resolution of ozonesonde measurements is specified. Lamina characteristics for Legionowo and Lindenberg, and small lamina (o2 mPa) characteristics for all stations suffer with effects of vertical resolution of measurements. For this reason they are not used here for long-term trend investigations. The long-term evolution of the ozone amount in one lamina does not display a trend. The results for the three remaining stations, Hohenpeissenberg, Payerne and Uccle, are largely consistent with our previous results on lamina behaviour, which means that our previous results on trends in laminae (e.g., Križan and Laštovička, 2005; Laštovička et al., 2014) are basically correct.
