An investigation of a possible dependence of brewer number 67's total-ozone measurements on some atmospheric parameters, together with a presentation of a peculiar synoptic ozone case at Rome

Abstract

Brewer total ozone data (January–December 1992) measured at the Physics Department, Rome University «La Sapienza» (41.9° North, 12.5° East) are analysed for dependence on Brewer internal temperature and some meteorological parameters. Non-parametric correlation analysis reveals the independence of total ozone from the internal Brewer temperature. Attention is focused on a peculiar case to show, by means of vertical wind velocity profile, the possible effects of lower stratospheric vertical advection on ozone fluctuations.
