Application of Raman Spectroscopy to Chemical Analysis of Atmospheric Particulate Matter
Abstract
Naturally emitted atmospheric aerosol particles are ubiquitous in the ambient outdoor atmosphere and within built environments of all kinds. They contribute to serious human health effects, climate radiative forcing, visibility reduction, acid and nutrient deposition to the Earth surface, changes in the hydrological cycle, and can act as agents of biowarfare. Yet for many of these processes, uncertainties in the aerosol properties often dominate the total level of scientific understanding or the ability to confidently detect the particles at all types. Raman spectroscopy of individual aerosol particles can offer a powerful ability to interrogate particles with a high degree of chemical identification in order to rapidly differentiate between benign and potentially dangerous species or to observe chemical changes that take places in the atmosphere that can alter their detection signatures.
