Abstract:

Aerosols influences the earths radiation balance and climate, atmospheric chemistry, visibility, and the health of living beings including humans on scales ranging from local to global. Recent studies indicate that aerosols present in the earths atmosphere are multi-component in their chemical make-up, and their microphysical properties and behaviors become very complicated to study. Given the impacts of particle composition on atmospheric chemistry and the radiation balance, understanding the nature of multi-component aerosol systems is fundamental to our understanding of their roles in the atmosphere. The ability to accurately measure and characterize these aerosols is also important in defense contexts for the detection of aerosolized biological and chemical weapons agents. The workshop proposed here will review the current knowledge of measurement and characterization techniques for aerosol systems and investigate what research directions are most likely to advance its capabilities. Examples of topics to review include mass spectrometry, electron microscopy, photoacoustic and nephelometry, laser-induced fluorescence, polarimetry, holography, and mobility spectrometers. This review will then enable general discussions between the workshop participants exploring coordinated research efforts intended to advance the field.
