AB: Biomass burning is considered to be a major source of atmospheric gases that lead to photochemical production of ozone, acid precipitation and increased particulate loading in the troposphere. The burning can also cause photochemical destruction of stratospheric ozone, and all of these effects can impact climate and air quality. Biomass burning has increased significantly on a global scale over the last 100 years. A warmer Earth resulting from global warming will lead to more frequent and larger fires especially in extra- tropical ecosystems presenting complicated scenarios for atmospheric research. We use satellite imagery and Geographical Information Systems (GIS) to analyze contemporary wild land fires and estimate trace gas and particulate emissions from global biomass burning events. The detection, frequency, and geographic and temporal distribution of these fire events will be presented. We will discuss their significance to the global budgets of trace gases, particulates and general air quality.
