Composition and origin of summertime air pollutants at Deep Creek Lake, Maryland
(Elsevier, 1989)
A 1 month intensive summertime field study conducted in rural western Maryland resulted in a comprehensive set of fine particle, gaseous and meteorological data. Sulfur in the assumed form of ammonium sulfate accounted for ...
Trajectory sensitivity to rawinsonde data resolution
(Elsevier, 1988)
Meteorological measurements collected during the Cross Appalachian Tracer Experiment (CAPTEX) were used to evaluate the sensitivity of trajectory calculations to variations in the spatial and temporal density of rawinsonde ...
On the variability of simulated source-receptor relationships for sulfur deposition
(Kluwer Academic Publishers; D. Reidel Publishing Company ; Springer Science+Business Media, 1986-10)
The use of Lagrangian models to estimate source-receptor relationships for ambient SO 4 = concentrations and S deposition has become fairly widespread over the past several years. This paper addresses the sensitivity of ...
Atmospheric acidity measurements on allegheny mountain and the origins of ambient acidity in the Northeastern United States
(Elsevier, 1989)
Atmospheric acidity as HNO3(g), SO2(g), and aerosol H+ was measured on Allegheny Mountain and Laurel Hill in southwest Pennsylvania in August 1983. The aerosol H+ appeared to represent the net after H2SO4 reaction with ...
Effect of ambient humidity on dichotomous sampler coarse/fine ratios
(Elsevier, 1988)
Atmospheric aerosols were measured in August 1983 on Allegheny Mountain and Laurel Hill in southwestern Pennsylvania. Ambient humidity was observed to influence the coarse to fine particle ratios as determined by dichotomous ...
Estimating the atmospheric input of pollutants into a watershed
(Kluwer Academic Publishers; D. Reidel Publishing Company ; Springer Science+Business Media, 1987-09)
Estimating the atmospheric input of ions to a watershed has traditionally been accomplished through either the extrapolation of point measurements of deposition or the integration of model estimated deposition. This paper ...
The influence of atmospheric transport on precipitation chemistry at two sites in the midwestern United States
(Elsevier, 1989)
Cluster analyses of two-dimensional mixed layer back trajectory data were used to determine what fraction of chemical variability in precipitation composition could be related to differences in atmospheric transport. ...
