Contents Notes
"The Clean Air Scientific Advisory Committee (CASAC) Ambient Air Monitoring and Methods Subcommittee (AAMMS, or the Subcommittee) met February 24-25, 2010 ... to review EPA's white paper on Particulate matter (PM) light extinction measurements ... The white paper was developed to assess possible technologies that could be used to measure light extinction. The assessment supports the on-going PM NAAQS review where EPA is considering a secondary standard that is protective of visibility The white paper presented options for direct measurement of light extinction as an indicator for a secondary standard and included a brief discussion of potential instruments. The white paper focused primarily on the use of a nephelometer to measure the scattering portion of the total light extinction due to PM and a filter transmission-based instrument for the absorption portion. The Subcommittee was asked to comment on the white paper and respond to the Agency's charge."--P. [1].
