The atmospheric constituents generated by the activities of an urban area may affect UV radiation reaching the ground. In this study, two areas were chosen in Baghdad city (Zafaraniyah and Abu Ghraib). Parameters of the pollutants data (Total column NO2 and Total column CO) and UV radiation for specific bands were collected and analyzed for the period of three years (2017-2019) were taken hourly from the European Center for Medium-Range Weather Forecasts (ECMWF) for each parameter through the years. The results show that the concentrations of pollutants in Zafaraniyah higher than Abu Ghraib throughout the year, Where total column NO2 reaching to about 9.6 * 10-5 kg m-2 in 2019 for Zafaraniyah and 8.48 * 10-5 kg m-2 for Abu Ghraib. While total column CO reaching to about 45 * 10-4 kg m-2 in 2019 for Zafaraniyah and 43 * 10-4 kg m-2 for Abu Ghraib in the same year. While the values of UV radiation in Abu Ghraib higher value 487.3W/m2 than 443.7 W/m2 Zafaraniyah throughout the year.
