Several past and ongoing visibility measurement programs in the rural western US have used ambient aerosol samplers of differing designs. These differences make a direct comparison of aerosol data from these studies difficult. In order to establish t

A pilot study was performed in order to gather data to determine the efficiencies of two nearby CO flares. Each flare stack was about 150 feet high with the thermal rise of the flare raising the resulting plume to about 200 feet. Since there are no r

The American Petroleum Institute (API) has developed data sets for the evaluation of dispersion modeling and optical remote sensing techniques. An initial field study (in Duke Forest, North Carolina) conducted in early 1995 at an open field site feat

In February 1997, a pilot study was set up to evaluate the use of open-path Fourier Transform Infrared (OP-FTIR) technology for the determination of emission factors for ammonia at a dairy farm, alfalfa field, and waste water treatment plant in the S

A description is provided of design considerations for a forthcoming cooperative field measurement study to evaluate optical remote sensing technology for potential use in directly measuring and/or inferring industrial air toxics emissions. The gener

An infinite set of ladder diagrams are summed to yield an augmented random phase approximation (ARPA) to the Bethe−Salpeter amplitude equation. The final equation is of the easily solved form of the RPA amplitude eigenvalue equation but with a more

Expressions are derived for the transition moments and absorption resulting from the electric moment induced in one molecule of a pair by the field of the quadrupole moments of a neighbor with axial or near axial symmetry. Values of relevant matrix e

The contributions of major source types to air quality and visibility in the desert southwestern U. S. near Page, AZ are determined for five distinctly different periods in June, July and December, 1979. The analysis is based on temporal and spatial

Aerosol chemical composition as a function of particle size was determined in the southwestern U.S.A. during four weeks of sampling in June, July and December, 1979 as a part of project VISITA. Samples were collected at two ground stations about 80 k
