There are two approaches for processing weekly temporal profiles: weekly normalization and weekday normalization. Although the actual normalization happens during temporal allocation, Smkinven sets the approach to use for each source. In the weekly approach, the Temporal program normalizes the weekly temporal profiles over every day of the week. This approach is appropriate for annual-total inventories or average-day inventories. Weekday normalization normalizes over just the weekdays (i.e., Monday through Friday) in the profile, or if the profile indicates no emissions on weekdays, then over just the weekend days in the profile. This approach is appropriate only for average-weekday inventories. Section 2.10, “Temporal processing” describes the two forms of weekly profile normalization in more detail.

The default normalization setting for IDA and ORL formats in Smkinven is weekly normalization. The default normalization setting for EMS-95 inventories is weekday normalization. The default settings can be changed using the WKDAY_NORMALIZE option in the SMOKE run scripts. When this option is set to Y, the sources will be set to instruct Temporal to use weekday normalization, and when this option is set to N, the sources will be set to cause weekly normalization. Smkinven gives a warning when an approach is being used that is inconsistent with the expected approach for the inventory format being used.
