The ATPRO, MTPRO, and PTPRO files are used by the Temporal program for area, mobile, and point sources, respectively. These files contain the monthly, weekly, and diurnal temporal profiles used to convert the annual emissions stored in the inventory to hourly emissions. The files can contain four types of records:
Monthly temporal weighting factors (/MONTHLY/ packet)
Weekly temporal weighting factors (/WEEKLY/ packet)
Weekday diurnal temporal weighting factors (/DIURNAL WEEKDAY/ packet)
Weekend diurnal temporal weighting factors (/DIURNAL WEEKEND/ packet)
The weekend diurnal temporal factors are optional. If the monthly factors are not used because all of the inventory emissions are supplied as “per day” emissions, at least one monthly profile is still needed, to prevent an error message. The file format is column-specific and shown in Table 8.54, “Format for ATPRO, MTPRO, and PTPRO”. All three source categories use the same file format, and they can share the same file.
