In Medford, Oregon, the major source of pollution is the lumber
mill waste burner. Its low combustion efficiency results in the
emission of large quantities of particulate into the atmosphere.
Due to the influence of the atmospheric radiation inversion and
possibly the poor performance of the burners at the time...
Open field burning is the lowest-cost method of harvest residue
disposal used extensively by grass seed producers in the Willamette
Valley of Oregon. The beneficial effects of open field burning include
effective disease control and increased seed yields. However, smoke
produced by open burning in the late summer pollutes valley...
The examination in some detail of the relationships between
air quality and the thermal structure of the lowest layers of the atmosphere
constituted the primary objective of this thesis. Data for
the study were assembled during April-June 1965 at the U.S.
Weather Bureau Station, McNary Field, Salem, Oregon. The measures...
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,...
