Source Category Codes Organic Profile File and Field Descriptions
SCCORG: The file used to link the organic profile data to the CEIDARS emissions. It also contains the SCC1N -> SCC8N fields, which contain categorical descriptions, and repeat the same fields in the SCCLIST file. These fields are not necessary for linking, and are included in the SCCORG file to simplify viewing.
- SCC: Field containing the Source Category Codes assigned to emission sources. This field may contain SCC codes (as used by the U.S. EPA and CARB) or EIC (Emission Inventory Code) codes, which are 14 digit codes defined and used by CARB. CARB uses both the SCC and EIC codes to define emissions in its CEIDARS database. These codes will allow you to link to the emissions estimates in the CEIDARS database, in order to speciate the emissions.
- ORGPRFCD: Field containing the organic profile code assigned to the speciation profile. This code is an arbitrary code assigned by CARB.
- SCC1N -> SCC8N: These fields contain descriptions that define nested categories. In other words, the SCC8N category description is also grouped within a broader category of SCC6N and on down though the nested categories to SCC1N, which is the broadest category, which is signified by a single digit of the code.

Using the data
The data in this file are used to link the WTFRACROG field in the ORGPROF file, as well as the WTFRACOFTOG field in the ORGSPEC file, to the SCCORG file via the ORGPRFCD field, and then to the CEIDARS emission data files via the SCC field.
