Development of a controlled combustion system for atmospheric and ecological studies
EMSL Project ID
60462
Abstract
Combustion carbonaceous aerosols (CCA) have important but poorly constrained climatic and ecosystem effects due to real-life combustion's chaotic nature, which leads to the generation of aerosols with a wide range of molecular properties. This project aims to enhance current EMSL capabilities by developing a tightly controlled (temperature and air-to-fuel ratio) combustion chamber compatible with multiple fuel types (e.g., fossil fuels and biomass) to enable mechanistic linkage of CCA and residual material to reaction conditions. Having precise control over formation conditions linked to EMSL capabilities for assessing the CCA’s physical, chemical, and optical properties will help elucidate CCA roles in atmospheric processing (e.g., atmospheric reactions, cloud formation activities, etc.) and effects on biosystem and ecosystem. CCA produced from this system will serve an additional role in calibration and testing of various aerosol-related EMSL instrumentation (e.g., Photoacoustic Spectrometer, Aerosol Mass Spectrometer, STAC, environmental sensors).
