Data for the U.S. Geological Survey Precipitation Chemistry Quality Assurance Project for the National Atmospheric Deposition Program, 1978–2017

The U.S. Geological Survey has operated the Precipitation Chemistry Quality Assurance (PCQA) Project to evaluate and document the data quality for the National Atmospheric Deposition Program (NADP) for 40 years. The PCQA is primarily focused on data quality for the NADP National Trends Network (NTN) and Mercury Deposition Network (MDN). The PCQA implements programs to evaluate the variability and bias of NADP data. The programs are described in several USGS reports: 1. See, R.B., Willoughby, T.C., and Brooks, M.H., 1990. Programs and analytical methods for the U.S. Geological Survey Acid Rain Quality Assurance Project: U.S. Geological Water-Resources Investigations Report 90-4029. 2. Latysh, N.E., and Wetherbee,...
