Abstract

The monitoring of the ozone amount in the global scale is concerned nowadays as a task that is of great significance for the life of our planet. For this purpose the Global Atmosphere Watch (GAW) network has been created and aimed to monitor the total ozone content (TOC) by set of ground-based instruments. Simultaneously, several projects like Total Ozone Mapping Spectrometer (TOMS) and Global Ozone Monitoring Experiment (GOME) sought to investigate the ozone from the space.
In this paper the results from the ground-based total ozone measurements performed at Stara Zagora , Bulgaria are presented and compared with the satellite (TOMS-EP and GOME) data. The ozone amount was determined using the scanning ultraviolet spectrophotometer Photon, which measures the direct solar UV radiation (290-360 nm) reaching the Earth surface.
    The analysis shows a good agreement between ground-based and satellite ozone data in the time period 1999-2005.Seasonal variations, typical for the middle latitudes – maximum in the spring and minimum in the autumn , are observed. The TOC changes for different months are examined. The biggest fluctuations of the TOC monthly average values are in the spring months and the smallest – in the summer months. There isn’t a statistically significant trend in the ozone column in the last three years.
