Atmospheric Aerosol Research-Atmospheric Aerosol Properties

We have developed techniques for measuring fundamental physical/chemical properties of atmospheric aerosols.  These include relative humidity-dependent equilibrium water content, particle density, particle refractive index, and particle shape.  Such information is needed when aerosol properties such as mass concentration, light scattering and absoprtion, and deposition on surfaces and in the lungs are calculated from measured size distributions.
