Due to the harsh natural environmental conditions in the Middle East and the fact that ozone is one of the top pollutants, research on ozone and its related pollutants has become more relevant in the countries concerned. This research is based on diverse datasets from the OMI instrument and utilizes backward trajectory analysis as well as Pearson spatial correlation to analyze the relationships between primary pollutant control zones during the warm seasons from 2010 to 2020 in the Middle East and meteorological factors. Research findings reveal the following.1. In terms of spatial distribution, ozone is primarily concentrated in the northwestern and central regions of the Middle East, while formaldehyde is predominantly found in the northern part of the region. Nitrogen dioxide, on the other hand, is mainly distributed in the northeastern portion of the Middle East. 2. In terms of time, ozone has shown a fluctuating upward trend since 11 years, with ozone considerably higher in summer than in winter; formaldehyde shows a higher winter than summer; and nitrogen dioxide shows a normal distribution. In order to facilitate environmental management, this study conducts an analysis of ozone-sensitive control areas within the research area at both annual and monthly scales. Results show that at the annual scale, ozone sensitivity is characterized by mixed or transitional control zones, while at the monthly scale, various control types are predominant.3. An analysis of the chemical and climatic processes involved in the formation of ozone showed a significant positive correlation between ozone and nitrogen dioxide, and an uncorrelated and weakly negative correlation with formaldehyde; ozone was positively correlated with temperature, and significantly negatively correlated with barometric pressure and relative humidity.4. Research on the HYSPLIT model and Weighted Potential Source Contribution Function for the elevated ozone regions in the Middle East indicates that the transport pathways of ozone pollution are primarily composed of two main components: the Persian Gulf and the Mediterranean.
