Meteorological Influences on Tropospheric Ozone Formation over the Tropical Atlantic Ocean As Observed during AEROSE Field Campaigns

Africa contributes to more than half of global biomass burning, releasing a substantial amount of harmful air pollutants that adversely affect human health. This emission releases significant quantities of ozone precursors into the lower atmosphere. The understanding of ozone distribution is pivotal in designing and enhancing satellite instruments that precisely measure ozone concentrations. In this study, we utilized data from multiple sources, including AEROSE Field Campaigns' ozonesondes from August 2009, July 2011, and November 2013, MERRA-2 reanalysis, and satellite data from the Integrated Multi-satellitE Retrievals for GPM (IMERG). Moreover, we employed laminar analysis to discern whether Rossby Waves or Gravity Waves were responsible for ozone induction. Based on previous research, our hypothesis leaned toward the prevalence of Rossby waves. However, the findings revealed that during each studied campaign, the proportion of Gravity Waves contributing to total ozone induction surpassed 70%. Furthermore, we conducted a comparative analysis between the model and actual data visualizations of ozone in the troposphere-stratosphere. Interestingly, a considerable amount of ozone was not detected by the MERRA-2 reanalysis. This observation underscores the importance of persistently exploring methodologies to enhance the accuracy of ozone level predictions, given their significant impacts on both human health and the climate.
