To help improve data quality for sensors applied in a nonregulatory fashion, which is growing in prevalence, the United States Environmental Protection Agency (EPA) is considering development of a new voluntary sensor certification program for air sensors. The objective of the report provided here was to evaluate peer-reviewed literature and other sources to identify performance attributes and metrics needed to obtain air monitoring data that are fit for a specific purpose or application. This literature review focused on reports associated with ambient and near-source air monitoring for particulate matter (PM_2.5 and PM₁₀), carbon monoxide (CO), nitrogen dioxide (NO₂), sulfur dioxide (SO₂), and ozone (O₃).
