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

This paper describes spatial and temporal variations of airborne paniculate matter in the eight western states included in the western fine particle network (WFPN). The samples were generated by a 40-site monitoring network of remotely sited dichotom

Mie scattering theory imposes strict requirements for both size and compositional information on aerosols associated with visibility degradation. But, at the very clean National Park Service sites where we do such studies, episodes of degraded visibi

The technique of background evaluation by using the spectrum of a blank substrate can, in principle, only be applied to spectra of lightly loaded aerosol samples with substrates having the same thickness as the blank. In this paper we present and dis

A detailed theory is presented for nucleation kinetics in emulsion polymerization systems based on the coagulation of precursor particles (which may themselves be formed by either homogeneous nucleation or micellar entry). These precursor particles d

The western part of the United States is characterized both by major scenic attractions (Grand Canyon, Yellowstone National Park, etc.) and the excellent visibilities necessary to enjoy the vistas. Recent legislation has been enacted to protect such

Monitoring of airborne pollutants in pristine areas is often hampered by the lack of electrical power and by difficult site access. Increased concern about effects of acid deposition in remote areas has necessitated development of appropriate samplin

Methods are described that allow additional information to be gained on aerosol parameters from samples suitable for PIXE analysis. In particular, these methods yield ways to directly compare the sum of all elemental species with total mass obtained
