Air trajectory and particle scattering data (bsp) for the period 1984-1989 are used to determine the relationship between atmospheric transport and visual air quality at the Grand Canyon National Park. Using cluster analysis, 72-hour back-trajectorie

Potential sources of pollutants can be identified by analyzing back trajectories associated with extreme ambient concentrations. Conditional frequency analysis (CFA) was used to identify statistically significant associations of geographical regions

The observed composition of visibility-reducing aerosols in the Grand Canyon region is summarized in climatological terms. Observations are from SCENES, a measurement program extending from 1984 to 1989. Results are presented as average mass balances

Since aerosol particulate sulfur is generally a secondary airborne pollutant, most source attribution techniques require many assumptions about the transport and chemistry of sulfur dioxide (SO2) emissions. Uncertainties in our understanding of these

Particle size distributions are sometimes conveniently described in terms of their integral moments. It is known that the details of a size distribution cannot always be recovered from its moments, but it has also been shown that an aerosol's optical
