The goal of this research is to examine the climatology and seasonal circulation patterns in West and Central Africa and investigate the relationship of biomass fires and tropospheric ozone levels of the Tropical Atlantic. High ozone levels in the tropical Atlantic have major implications for global atmospheric chemistry and potential environmental effects throughout the tropics. The principal investigator is utilizing visible and infrared satellite imagery and numerical modeling of selected case studies to isolate key transport mechanisms for ozone and ozone precursors. The project involves significant collaboration with African scientists.

这项研究的目的是研究西非和中部非洲的气候学和季节环流模式，并调查生物质火灾与热带大西洋对流层臭氧水平的关系。热带大西洋的高臭氧水平对整个热带地区的全球大气化学和潜在的环境影响具有重大影响。首席调查员正在利用可见光和红外卫星图像和选定案例研究的数值模拟来分离臭氧和臭氧前体的关键传输机制。该项目涉及与非洲科学家的重大合作。
