9722-9ED - Collection of Basic Precipitation Records

Problem - Precipitation quantity and chemistry are parameters used in various hydrologic studies along with runoff, recharge, and evapotranspiration. Variations in these data are needed as a part of the National Trends Network (NTN).

Objectives - To determine variations in precipitation quantity and quality at Pullman, Washington, as part of the nationwide NTN.

Relevance and Benefits - An important part of the USGS mission is to provide scientific information to manage the water resources of the Nation, and to enhance and protect our quality of life. The USGS is the lead Federal agency for monitoring wet atmospheric deposition (chemical constituents deposited from the atmosphere via rain, sleet, and snow) in the United States. In cooperation with more than 100 Federal, State, and local organizations, the USGS provides long-term atmospheric deposition data from a national-scale network of more than 200 sites. All data from this network are made available on the World Wide Web. The network provides data in support of research on air quality, water quality, forest productivity, materials effects, ecosystem studies, watershed studies and human health, and a national baseline with which to evaluate the effectiveness of ongoing and future regulations intended to reduce atmospheric emissions and subsequent impacts to terrestrial and aquatic ecosystems. The atmospheric deposition data collected in this State are an integral part the nationwide atmospheric deposition network.

Approach - Operation of a rain gage and precipitation sampler to collect chemistry and quantity data in accordance with NTN guidelines.
