SPECIATE is the EPA's repository of total organic
compound (TOC) and particulate matter (PM) speciation profiles of air pollution sources.
Among the many uses of speciation data, these source profiles are used to: 1) create speciated
emissions inventories for regional haze, particulate matter (PM2.5), and ozone (O3) air quality
modeling; 2) estimate hazardous and toxic air pollutant emissions from total PM and TOC
primary emissions; 3) provide input to chemical mass balance (CMB) receptor models; and, 4)
verify profiles derived from ambient measurements using multivariate receptor models (e.g.,
factor analysis and positive matrix factorization). SPECIATE 4.0 replaces the prior
version of the SPECIATE version 3.2 released November 2002. It includes a total of 4,080 PM and TOC profiles including 2,019
new profiles. |

| The process of calculating the VOC-to-TOG conversion factor for a given profile consists of determining the organic gases in the profile that are exempted from the EPA VOC definition and determining what portion of the overall profile is composed of these non-photochemically reactive compounds. - Memo: VOC-to-TOG Conversion Factors - June 2005, revised September 2005.
