This page last reviewed March 13, 2013
Guidance - The ARB and the US EPA offer guidance for use by those submitting
inventories.
Mobile Source Models - Government and other organizations involved in inventories, database format specifications,
quality assurance procedures, statewide and district quality assurance reports.
Area-Wide
Source Methods - The ARB and the districts have developed
over 460 of estimation methods for area-wide sources.
Reference - The emission inventory uses a number of unique code systems to represent such
things as industry and process type. Emission factors are used to calculate emissions and are specific
to individual pollutants and process types.
Speciation
Profiles -- Speciation profiles
estimate the composition of emissions and are used in the emission inventory and air quality models.
The ARB maintains estimates of the chemical composition and size fractions of particulate matter (PM) and the
chemical composition and reactive fractions of total organic gases (TOG) for a variety of emission source
categories.
Software - The ARB and the US EPA have created a number of software tools to store and
create emission inventories.
