Data Quality Reports

This page last reviewed October 31, 2017

The purpose of the data quality report is to provide ambient air quality data producers and users with a centralized review of the data quality within ARB’s Primary Quality Assurance Organization (PQAO).  The report describes the quality of the ambient air quality data in quantifiable terms in relation to measurement quality objectives established by U.S. Environmental Protection Agency.  Starting in 2011, the report focuses primary on the precision and bias/accuracy of gaseous criteria and particulate matter measurements and the amount of such data collected and reported.  Tables included in the report provide summary data for ambient air monitoring stations in the statewide network within ARB’s PQAO, with comparisons to other PQAOs where appropriate.
