AbstractIn this work, we depend onmeteorological information data taken from the Europeans Center for Medium Weather Forecasting (ECMWF).Four selected position have been investigated in Iraq : Baghdad, Basra, Mosul and Rutbathrough the whole year rangefrom 1 /1/2009 to 31/12/2009.
Also,month-hourly concentrations average have been investigated for CO, NOxconcentration , as well as , the correlation of the monthly average of CO , NOx concentration with temperature and estimatethe simple linear regression for this correlation so as to show the temperature effect on the pollutant concentrations. It found that higher monthly-hourly concentration for CO, NOx concentrations at six clock (06:00)in the morning and lower monthly-hourly concentration at six clock(18:00)in the evening at all studied position. We have concluded effect correlation of temperature on pollutant concentration it was revers correlation, whenever the temperature increased, the pollutant concentration decrease.
Higher correlation between temperature andpollutant concentration of appeared in heavypopulation areas due to human activity in different fields and that lead us toconclude two formulas. We can through these two formulas estimate pollutants concentration average and temperatureaverage if the data available of the two variables for the same studied periods.
