| Area-Wide source methods are used to estimate emissions for approximately
500 emission source categories in the emission inventory. Also, we provide more information on the area-wide source
emission categories. |
| The Index
of Methodologies by Major Category includes summaries of the methodologies with links to the complete methodologies,
which are provided in Acrobat format. A detailed list of the area-wide source categories is provided in the
List of Area-Wide
Source Categories and the Responsible Agency in Acrobat
format. To calculate the emissions from off-road mobile sources, ARB staff has developed an off-road mobile source
emission model, OFFROAD. Information on recent updates to
the OFFROAD model is available for review. |
| This website is a living document, which means individual sections will
be updated periodically as individual categories are updated or new categories are created. Draft methodologies recently developed by ARB staff are available for review in Acrobat format. If you
have questions or suggestions concerning these methods, please email the Emission Inventory Branch. Also, available
are methodologies recently developed by Sonoma Technology, Inc. (STI) for the Central California Ozone Study
(CCOS). Please view the STI methodologies. |
