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...
Precipitation occurrence in three winter periods and three
summer periods is examined for two Oregon stations: Seaside and
Squaw Butte. The winter periods are January, February, and the
interval January 15 to February 20. The summer periods are July,
August, and the interval July 10 to August 15. The two...
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...
This study examines in detail a continuous drop-size distribution
recorder and selected data gathered with this recorder at
various locations on 6, 15, and 31 May 1966. The drop-size distribution
recorder consists of a self-contained, mobile unit able to
operate without electric power. This recorder utilizes "Ozalid 105
SZ" filter...
This investigation studies the relationship of the reflectivity in
the radar beam depicted by the radar echo patterns to the computed
reflectivity at surface observing stations under the radar beam.
Drop size distributions at stations in the Oregon State University
Mesometeorological Network during the storm period of 27-30 March
1963...
Detailed analyses of snow crystal sequence and atmospheric
conditions were accomplished utilizing macrophotographic techniques
for obtaining the snow crystal record at Santiam Pass in the Oregon
Cascades on 19-20 January, 14-15 February, and 9-10 March, 1967.
The photographic equipment consisted of a 35 millimeter single lens
reflex camera, bellows, and...
In 1959 the British Ornithological journal, The Ibis, published a centenary commemorative volume on the history of ornithology in Britain. Over the previous few decades, the contributors to this volume had helped focus the attention of ornithologists on the methods, priorities, and problems of modem biology, specifically the theory ofevolution...
