The PTHOUR file is the input point-source inventory file for hour-specific data and profiles. The file must be a list file (see Section 8.2.1.1, “Inventory list files” and the files listed in the PTHOUR file must be in Continuous Emissions Monitoring (CEM) format when processing hourly CEM inventory data files with an format
identifier (#CEM) or the format can be specified in the PTHOUR list file (#LIST CEM). In addition, these files can have a #COUNTRY entry to set the country code (see Section 8.2.1.4, “Header records”. The default country code is 0, which corresponds to the United States in the default COSTCY file.
The PTHOUR file may optionally contain a packet to control the range of dates for which Smkinven will read data. When this feature is needed, the following entry should appear on the first line of the PTHOUR file.
DATERANGE MMDD(start) MMDD(end)
where MMDD is the two-digit month and day of the month at the start and end of the period of interest. For example, to request July 10th through 12th, the first line of the file should read:
DATERANGE 0710 0712
The year is implied by the data themselves; note that the files can only contain data for a single year. As an alternative
to using the DATERANGE packet, you can manually break the year up into smaller periods in separate files, and only list the
files of interest in the PTHOUR file. Note that reading in the whole year of data and extracting just a few days will take much more time than manually editing
the file to contain just the days of interest. Also note that if you choose the manual editing option, you must select days
that fully cover the modeling episode after accounting for time zone differences between the facility’s time zone and the
modeling time zone (set by the OUTZONE option).
SMOKE uses the CEM ORIS ID and Boiler ID fields to match sources in the CEM hour-specific inventory to those in the annual inventory. Note that the CEM data hours are in standard local time (no daylight saving time adjustment). The format of the CEM hour-specific data is shown in Table 8.22, “CEM Format for individual hour-specific data files”.

This FF10 format uses the header described in Section 8.2.1.4, “Header records”.
The user specifies the data provided using this command in the header: FF10_HOURLY_POINT.
Sample header records for hourly point sources are shown below:#FORMAT=FF10_HOURLY_POINT #COUNTRY US #YEAR year of inventory, e.g. 2008 #DESC Point Hourly Source Inventory #DESC FF10 Point Hourly format
