Abstract :Meteorological factors have a significant impact on the formation and transport of tropospheric ozone. In addition to the meteorological factors, solar radiation and associated chemical reactions, topography, and pollution sources also affect the ozone concentration levels insert ignore into journalissuearticles values(O3);. In this study, the influences of the meteorological factors insert ignore into journalissuearticles values(temperature, wind speed, relative humidity, solar radiation); on O3 were investigated for Çanakkale throughout the 2014-2018 period. It was found that O3 concentration levels in summer season are linked with the high humidity and, especially high temperature. The statistical analysis indicated that O3 concentrations at Çan district insert ignore into journalissuearticles values(SE Çanakkale); were positively correlated with temperature during summer and autumn seasons insert ignore into journalissuearticles values(r=0.53);. Similarly, a statistically significant positive correlation was found at Lapseki station of Çanakkale during autumn insert ignore into journalissuearticles values(r=0.48);, spring insert ignore into journalissuearticles values(r=0.41);, and summer months insert ignore into journalissuearticles values(r=0.40);, respectively. On the other hand, relative humidity insert ignore into journalissuearticles values(RH); displayed negative correlations with O3 at Çan and Lapseki stations. In addition, negative correlation was observed between nitrogen oxides insert ignore into journalissuearticles values(NOX); and O3 values measured at Lapseki station. The main important factors affecting ozone concentration levels in Çanakkale were found as local meteorological conditions and long-range transportation of pollutants from anthropogenic sources insert ignore into journalissuearticles values(e.g. vehicle, industrial emissions, volatile organic compounds insert ignore into journalissuearticles values(VOCs); emitted from solvents and industry);.
