| This poster deals with the dependence of ozone lamina characteristics trend at the European ozonosonde stations to small changes in lamina definition. We change the depth of lamina( 3500,2500 and 1500 m), sharpness of laminae size of laminae (20,30,40nbar) and second minimum definition . We use data of vertical profile of ozone concentration from these European stations which have long series of ozone vertical profile observations: Hoheipeissenberg, Payerne, Uccle, Legionowo and Lindenberg. |
