Abstract |
The atmospheric visibility-reducing aerosol in the Southwest has been experimentally characterized with respect to particle size, composition, and contribution to light scattering. Measurements were taken within the mixing layer using the MRI instrumented Beechcraft Queen Air aircraft. The aircraft was equipped to measure and record on magnetic tape the light-scattering coefficient, Aitken nuclei count, size distribution, ozone, sulfur dioxide, nitrogen oxides, temperature, dew point, turbulence, pressure (altitude), and navigational parameters. Multistage impactor and size-fractionated filter samples were also collected in order to determine aerosol elemental composition as a function of size. Visual range estimates were obtained by viewing distant landmarks and verified by optical photography. |
