An integrating nephelometer was set up at the Eugene Airport
which is located five miles north of Eugene, Oregon, on Highway
99 West. Continuous atmospheric scattering coefficient readings
were obtained from July 1, 1969, to August 28, 1969. These data

Many agricultural fields are burned in the Willamette Valley
of Oregon during the summer for economic reasons. A major air
pollution problem results from these burnings. The purpose of this
study was to develop relations between the maximum plume height
and some of the independent variables affecting this plume height,...
Ammonium chloride aerosols of submicron size generated by
condensation and dispersion methods were treated, shortly after aerosol
charging, with shock waves originating from diaphragm pressure
ratios of up to 5.75.
The fraction of the particulate matter remaining in suspension
after a given time was measured as an indication of coagulation...
