Impact/Purpose:

A comprehensive literature review of lrecent published accounts of ow cost sensor use and their reported performance measures. Discussion of regulatory-based air quality performance measures from a US and international perspective as it relates to the criteria air pollutants.

Description:

Recently, the rapid growth of miniaturized, lower-cost air sensors is changing the landscape of air pollution monitoring to enable cities, civil society, businesses, and consumers to monitor local air quality conditions, though with accuracy not on par with reference techniques. Unlike more expensive instruments with comprehensive, codified regulatory standards and performance certification processes, few standards or certification procedures exist for these new lower-cost air sensors. The lack of accepted performance specifications for air sensors is limiting the understanding of the quality of the data produced with this emerging technology and is leading to confusion in the marketplace, as new buyers are uncertain of how well air sensors currently perform, how to operate (e.g., calibrate) them, and how well sensors need to perform to be suitable for a given purpose. This work focused on informing the development of performance requirements for air monitoring instruments that measure particulate matter (PM2.5 and PM10), carbon monoxide (CO), nitrogen dioxide (NO2), sulfur dioxide (SO2), and ozone (O3).
