摘要：
Nitric acid, particulate nitrate, and particulate sulfate samples were collected on filter media on an approximately weekly basis between 26 October 1989 and 26 September 1990 at a mountain site in southern Nevada, U.S.A. Wind velocity and direction data were obtained for each sampling date from two locations in the nearby urban area of Las Vegas, NV. Seasonal differences in species concentrations are correlated to the seasonal meteorology; transport of nitrate from distant sources may be prevalent during part of the year.
