The possible impact of cosmic rays to the total ozone column in Athens, Greece

Περίληψη

During the last decade a number of studies have indicated connection between cosmic rays / solar activity and climatic parameters. The present study investigates the possible variation of cosmic rays / solar activity signal in a total ozone column above mid latitude Mediterranean city of Athens, Greece. The daily data used, covered 1978 - 2012 time interval while they included daily: multi sensor reanalysis data sets for ozone column, sunspot number from omniweb datasets and cosmic rays data from Moscow Neutron Monitor datasets. The results indicated a clear signal of solar activity variation (positive / negative and vice versa) in the total ozone column.
