Precipitation Records

Data on variations in the quantity and chemical make up of precipitation provide important information for research on hydrology, air quality, water quality, forest productivity, materials effects, ecosystem studies, watershed studies and human health. A national database can provide a baseline with which to evaluate the effectiveness of ongoing and future regulations intended to reduce atmospheric emissions and the subsequent effects on terrestrial and aquatic ecosystems.

As the lead Federal agency for monitoring wet atmospheric deposition (chemical constituents deposited from the atmosphere by rain, sleet, and snow) in the United States, the USGS, in cooperation with more than 100 Federal, State, and local organizations, provides long-term atmospheric-deposition data from a national network of more than 200 sites. All data from this network are part of the National Trends Network and are available on the World Wide Web. The atmospheric-deposition data collected at Pullman, Washington, are an integral part the nationwide atmospheric-deposition network.
