Abstract

Tropospheric ozone cartography was established for the first time over the north of Algeria in this work. A set of 50 passive sampling tubes were distributed over Algiers city. The cartography was carried out by the ArcGIS software. The results shows that the highest O³ levels were mainly recorded in the east part of Algiers and to a lesser degree, in the west part. In addition, the ozone data of the Algiers Air Quality Monitoring Network was used to test the RAMS-EPS3-CAMx model system for ozone over the north of Algeria. It shows that there is relatively good agreement between the measured and predicted data with a clear diurnal ozone distribution. The ozone spatial evolution obtained from observation and modelling was relatively similar albeit some registered deviations.
