Experience and Illumination of Data Quality Assessment System for Ambient Air Monitoring in the United States

After the authority of urban automated monitoring stations in the ambient air quality monitoring network of China was transferred to the national government, considering the requirement for evaluating the monitoring corporation, assessing the data quality of national monitoring network and preparing the data quality report, the quantitative evaluation for the precision and accuracy of air monitoring data was urgently needed. In order to strengthen the construction of the ambient air data quality assessment system in China, this article summarized the ambient air monitoring data quality assessment system and relevant technical regulations in the U.S., introduced the characteristics of each audit program, and presented suggestions for the construction of ambient air data quality assessment system in China.
