Chemistry of Atmospheric Deposition - Effects on Agriculture, Forestry, Surface Waters, and MaterialEntry ID: USDA0422
Abstract: The "Chemistry of Atmospheric Deposition - Effects on Agriculture, Forestry,
Surface Waters, and Material" is a dataset that contains weekly measurements of
rainfall and chemistry, including pH, conductivity, Na, K, NH4, Ca, Mg, NO3,
SO4, and Cl. The purpose of this dataset is to measure and characterize the
supply of beneficial and injurious chemical substances in atmospheric
deposition across ... the United States; to determine the spatial patterns and
temporal trends in the distribution of biologically important chemical elements
that are deposited on natural and managed ecosystems, including croplands,
pasture, and rangelands, forests, wetlands, and lakes and streams; and to
determine the effects of atmospheric deposition on the productivity and
chemical composition of soils, and the survival and productivity of wildlife,
fish and domestic food animals.
Collection Organization: Virginia Polytechnic Institute
Collection Methodology: A large network of researchers is cooperating to
characterize chemical deposition from the atmosphere and assessing its effects
in North America. This network consists of 168 scientists in 11 state and
federal agencies and more than 20 universities. VPI & SU will contribute to
this network by serving on the Effects Research Committee, operating one
station for collecting chemicals deposited from the atmosphere, and developing
experiments to determine the effects of these chemicals on plants.
Collection Frequency: Weekly.
Update Characteristics: Updated in its entirety.
Data Center: Virginia Polytechnic Institute
Dissemination Media: Hard copy, digital, online
File Format: ASCII files.
Access Instructions: Contact the data center for instructions on
how to access the data online.
Access Restrictions: None.
