摘要：Total Ozone Column (TOC) measured by Total Ozone Mapping Spectrometer (TOMS) broad on Earth probe (EP) for Baghdad city (Lat 33.35 No, Long 44.45 Eo) has been analyzed. The results give the estimate means and variability of temporal scale. Using linear regression, results shows that TOC has a trend of – 0.333 DU per year. The maximum and minimum day to day variation of TOC were 40.9% (121DU) and 22.4%(-66.3DU) respectively. A spectral analysis on daily values shows that the dominating oscillation periods are between 2.8 and 5.4 days. Solar activity has a weak effect on total ozone production with correlation coefficient (0.22).
