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 either EMS-95 format or Continuous Emissions Monitoring (CEM) format. Each file must have an format identifier
(either #EMS-95 or #CEM) or the format can be specified in the PTHOUR list file (#LIST EMS-95 or #LIST CEM). The contents of the hour-specific data files vary depending on whether the PTINV file is in EMS-95 or IDA format. 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).
For EMS-95 formatted data, SMOKE requires that the sources in the PTHOUR file also be in the PTINV file. The values of the fields that are common to the hour-specific data and the annual data need to match exactly. These
fields are Facility ID, Stack ID, Device ID, and Process ID. These fields are treated as text fields (not numeric) in SMOKE,
so leading zeros need to be consistent between the hour-specific and annual or average-day inventory files.
To process pollutant names greater than 5 characters, you need to add the new field of inventory pollutant code known as CAS
number from column 261 to 276. If this new field is filled, the POLID is not used. If the new field is not filled, the POLID is required to use the inventory data name. The CAS number will be used to distinguish which chemical compound or inventory
pollutant is provided on each line of the file. Smkinven matches these numbers with teh CAS numbers from an inventory table (INVTABLE) file, described in Section 8.10.3, “INVTABLE: Inventory table”. The CAS number does not necessarily have to be a valid CAS number; it can be any number as long as there is a match between
the numbers in the SMOKE ORL file and the inventory table.
When using hour-specific data in EMS-95 format with the IDA annual inventory, the fields in the PTHOUR file should line up with the fields in the PTINV file as follows:
PTHOUR Facility ID (FCID) maps to PTINV PLANTID
PTHOUR Stack ID (SKID) maps to PTINV POINTID
PTHOUR Device ID (DVID) maps to PTINV STACKID
PTHOUR Process ID (PRID) maps to PTINV SEGMENT
PTHOUR SCC (implied by Process ID in EMS-95 process file) maps to PTINV SCC
The EMS-95 format for hour-specific data is shown in Table 8.42, “EMS-95 Format for individual hour-specific files”.

The CEM hour-specific format can only be used with IDA-formatted annual inventory files. SMOKE uses the CEM ORIS ID and Boiler ID fields to match sources in the CEM hour-specific inventory to those in the IDA-formatted 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 8.43, “CEM Format for individual hour-specific data files”.
