SPECIATE Version 3.2

Return to SPECIATE 4.2

SPECIATE 4.0 was released January 17, 2007. It superscedes all previous versions of the software. Version 3.2 will remain on the EPA website for your convenience.

November 2002: SPECIATE is EPA's repository of Total Organic Compound (TOC) and Particulate Matter (PM) speciated profiles for a variety of sources for use in source apportionment studies. This release of SPECIATE no longer contains profiles assigned to SCC's. Instead, searching for profiles by keyword has been improved and of course the user can still browse through the profiles. Some additional improvements have been made to the interface, and some minor bugs associated with the export feature have been fixed. No new profiles have been added to SPECIATE since the previous release in October, 1999.

An expert panel of potential SPECIATE users and data suppliers was convened at the October 2002 American Association for Aerosol Research (AAAR) Conference in Charlotte, NC to re-evaluate speciation needs. The minutes and recommendations from the meeting and a bibliography of potential journal articles containing newer profile data are in a table below.

SPECIATE 3.2 is a 32-bit program that can run under Windows 95/98 or Windows NT. The single file install version EXE file is a self-extracting 2.8 MB file.
