Abstract: The most important issues of concern to the world is depletion of the Ozone layer and its related to the climate change, which is always focused on the relationship between them through the temperature change. The aim of this research is to study the variation of Ozone layer and temperature above Iraq (latitude 28-38oN, longitude 38-49oE) for the years (2002-2016). The data for the monthly average total Ozone column (TCO3) and the temperature (T2m) are taken for two times (0000 and 1200 UT). Three Iraqi cities are chosen for this study Dahuk, Baghdad, Basrah which represents the North, middle and South of Iraq respectively. It is found that in general, the TCO3 in day time greater than night where the difference between night and day about 1-22 DU. Regarding to temperature T2m, the difference between day and night about 9-12oC. In North the values of TCO3 are greater than middle and South. About the seasonal fluctuations, the values of the TCO3 in spring and winter are greater than summer and autumn, it reaches maximum in 2016 about 410 DU and the minimum in autumn about 260 DU. It is found from the results that there is an inverse relation between TCO3 and T2m along period study in Baghdad and Dahuk, but in Basrah the relationship fluctuated between increasing and decreasing.
