Abstract
Daily total ozone data derived by means of a Brewer spectrophotometer at Rome (Italy) during the European Arctic Stratospheric Ozone Experiment (EASOE) were subjected to time series analyses to investigate any possible variations.
Graphical and statistical analyses revealed the existence of below-normal occurrences of total ozone for the months of January and February in both winters. In an effort to filter out the influence of natural fluctuations on the observed below-normal ozone occurrences, long-term Dobson total ozone records (from 1957 to 1986) of Vigna di Valle station (Rome) were analyzed to ascertain the existence of the respective high and low frequency variations. The removal of short-term fluctuations shows that mean ozone values are still below normal. UV-B data collected within the same period are also considered.
A trend analysis of the ozone time series of Vigna di Valle (Rome) station shows a decreasing tendency in the last ten years, particularly during the winter season.
