This forecast is important for monitoring O3 concentrations at a regional scale as well as at local level. We used the monthly average O3 concentrations covering the period going from January 2003 to December 2011. The accuracy of the models has been carried out with predicting and analyzing the average monthly O3 concentrations for 2012. By comparing the measured O3 concentrations values and the forecasted values, the AR(1) model is satisfactorily predicts monthly average O3 concentrations in the Assekrem area and the predictions of this model are loosely consistent with the measured values. The developed model can be used to forecast atmospheric tropospheric ozone concentrations in Assekrem area.
