This article provides O 3 results to incorporate into reports and research studies. The monitoring of O 3 levels in the ambient air of Oujda during warm and the cold seasons respectively is needed, justified, discussed and interpret the O 3 measurements. During the warm season 60.07% of the recorded values are below the Moroccan limits and 41.1% are below world health organization limits, in the second sampling campaign (in cold season) 92% of the recorded values are below the Moroccan limits and 84.6% are below world health organization limits. This article provides background information on O 3 formation, sources, and a comprehensive review of probable O 3 impacts and also describes the monitoring of O 3
