SPECIATE 5.1 Documentation
These documents describe the SPECIATE database, EPA’s repository of organic gas and particulate matter (PM) speciation profiles for air pollution sources.
Documentation is provided for the SPECIATE 5.1, which is an addendum to the documentation for SPECIATE 5.0. These two versions are the most recent versions of SPECIATE. The addendum summarizes the SPECIATE program and provides the changes to the database since SPECIATE 5.0. The SPECIATE 5.0 final report provides a full history of the SPECIATE program.
Documentation for earlier versions of SPECIATE including SPECIATE 4.5, SPECIATE 4.4, SPECIATE 4.3, SPECIATE 4.2, and SPECIATE 4.0 can be found in the SPECIATE Documentation Archive linked below.
