Long-term Dynamics of the Total Ozone over Bulgaria
Abstract
For the first time long-term observations of the ozone column over Sofia (42° 39' N, 23° 23' E), Bulgaria, are described and analysed. Total ozone observations over Stara Zagora, Bulgaria, are also presented. Ozone measurements have been carried out using filter ozonometer M124 (Sofia) and scanning ultraviolet spectrophotometer "Photon-2" (Stara Zagora). The groundbased measurements are compared with data from the TOMS and GOME satellite experiments. The paper deals with the following issues: analysis of the differences between the total ozone measurements from ground and space-borne instruments; examination of the long-term variations of the total ozone monthly mean values: 1989-2001 (Sofia) and 1998-2007 (Stara Zagora); study of the tendency detected in the total ozone annual behaviour.
