Spatial and seasonal trends in particle concentration and optical extinction in the United States
In the spring of 1988 an interagency consortium of Federal Land Managers and the Environmental Protection Agency initiated a national visibility and aerosol monitoring network to track spatial andExpand
Seismicity and shape of the subducted Nazca Plate
An updated compilation of earthquake locations and focal mechanism solutions from the International Seismological Centre and Preliminary Determination of Earthquakes is the basis of a comprehensiveExpand
Asian aerosols in North America: Frequency and concentration of fine dust
average) are between 0.2 and 1 mg/m 3 and only very rarely exceed 5 mg/m 3 . Our data also indicate that Asian dust is concentrated in an altitude zone ranging from about 500 to 3000 m MSL,Expand
Long‐range transport of North African dust to the eastern United States
The long-range transport of North African dust to the Middle East, Europe, South America, and the Caribbean has been well documented during the past 25 years. With the advent of routine collectionExpand

Based on instrument performance, the BAM, the integrating nephelometer, and the CAMM appear to be suitable candidates for deployment in a real-time continuous PM2.5 monitoring network in central California for the range of winter conditions and aerosol composition encountered during the study.

ACE-ASIA Regional Climatic and Atmospheric Chemical Effects of Asian Dust and Pollution
Although continental-scale plumes of Asian dust and pollution reduce the amount of solar radiation reaching the earth's surface and perturb the chemistry of the atmosphere, our ability to quantifyExpand
Elemental characterization of particulate matter emitted from biomass burning: Wind tunnel derived source profiles for herbaceous and wood fuels
Particulate matter emitted from wind tunnel simulations of biomass burning for five herbaceous crop residues (rice, wheat and barley straws, corn stover, and sugar cane trash) and four wood fuelsExpand
Saltating Particles, Playa Crusts and Dust Aerosols at Owens (dry) Lake, California
As part of the multinational Lake Owens Dust Experiment (LODE), we have studied the generation of dust storms on the south sand sheet of Owens (dry) Lake, California, an anthropogenically desiccatedExpand
Long-range transport of anthropogenic aerosols to the National Oceanic and Atmospheric Administration baseline station at Mauna Loa Observatory, Hawaii
Size-segregated measurements of aerosol mass and composition are used to determine the composition and seasonal variations of natural and anthropogenic aerosols at Mauna Loa Observatory (MLO) fromExpand
Relation of vertical flux of particles smaller than 10 μm to total aeolian horizontal mass flux at Owens Lake
The vertical flux of particles smaller than 10 μm for a saline playa surface, the particle size composition of which was classified as loam-textured, was estimated for a highly wind-erodible site onExpand
