We are studying a series of model aerosols generated under realistic conditions using small engines and photochemical smog in a roof-top Teflon reaction chamber (shown at left). Aerosols are characterized with an extensive suite of techniques including in situ optical and
off-line optical to off-line mass and composition analyzers.
Polar Nephelometer: A new, light, rugged instrument to measure angular scattering is being developed, verified, and applied. Refractive index data is being retrieved from the data using a genetic algorithms approach.
