The collection of precipitation and the measurement of its constituents are important steps in attaining a better understanding of the distribution and effects of acid rain in the United States. The document is a report of the findings from quality assurance and technical assistance visits made in 1987 to the 29 sites that comprise the State Operated Precipitation Network. The network is staffed mainly by personnel from state environmental agencies and foresty commissions. It is under the overall sponsorship of regional and national offices of the Environmental Protection Agency. Procedures followed in conducting the site visits are described. Results of systems and performance audits are discussed for siting, collection equipment, and field laboratories.
