Precision and Accuracy Assessments for State and Local Air Monitoring Networks, 1981-1986

摘要

Precision and accuracy assessments of air quality data obtained from State and local air monitoring agencies during the six years, 1981-1986, are summarized in graphical form for each reporting organization. For most reporting organizations, the graphs show an improvement in data quality during the six-year period. Comparisons across reporting organizations for the same pollutant measurements reveal persistent significant differences. The data quality assessments are also summarized and shown graphically for each EPA Region and for the Nation. The report covers the period from 1981 through 1986.
