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.

这项研究的目的是检查西非和中非的气候和季节性循环模式，并研究热带大西洋的生物质火与对流层臭氧水平的关系。 热带大西洋的高臭氧水平对全球大气化学和热带地区的潜在环境影响具有重大影响。 主要研究者正在利用可见的红外卫星图像以及所选案例研究的数值建模来隔离臭氧和臭氧前体的关键运输机制。 该项目涉及与非洲科学家的重大合作。
