The ATREF, MTREF, and PTREF files contain the area-, mobile-, and point-source cross-reference records for assigning the temporal profiles to the sources.
If needed, the same file can be used for area-, mobile-, or point-source categories, but more fields are used for mobile than
for area, and more fields are used for point than for mobile. Section 6.16, “Temporal” provides a list of the matching hierarchies that SMOKE uses when applying the file to an inventory. If a field is blank, it must be set to -9.
Between weekly and daily temporal profiles, daily Profiles will take precedence weekly profiles. Within hourly diurnal profiles,
the processing occurs as follows (1) day-to-hour hourly profiles (i.e., Monday,,,,,Sunday), (2) Weekday/Weekend hourly profiles,
and (3) All days (Monday-Sunday) hourly profiles. However, date-specific houlry temporal profiles from [A|M|P]TPRO_HOURLY_NCF input file will take precedence any types of temporal profiles. This date-specific hourly temporal profiles NetCDF input
file contains annual total (ANNTOT), monthly total (MONTOT), daily total (DAYTOT) and hourly total (HRLTOT) to compute year-to-hour, month-to-hour, day-to-hour profiles to calculate hourly total depending on types of inventory data
(annual, monthly or daily inventory). If inventory is annual total, year-to-hour profiles will be used to convert annual total
to hourly total emissions. If inventory is monthly total, month-to-hour profiles will be used to compute hourly total from
monthly total inventory.
Within the Temporal program, the processing occurs as follows:
Temporal profiles are assigned for all sources.
Monthly (year-to-month) temporal profiles can be applied.
Daily (month-to-day) temporal profiles can be applied.
Weekly (month-to-weekly) temporal profiles can be applied.
Day-of-week specific hourly diurnal temporal profiles (Monday,,,Sunday, Weekday, Weekend, or All days) are applied.
Date-specific hourly diurnal temporal profiles (year-to-hour, month-to-hour or day-to-hour) can be applied.
Day-specific emissions or activities are read in and used to overwrite daily emissions for the appropriate sources
Hour-specific emissions or activities are read in and used to overwrite hourly emissions for the appropriate sources.
NOTE: Date-specific houlry diurnal temporal profiles require FIPS and SCC specific entries in [A|M|P]TREF input file.
The pollutant field allows the user to assign a different temporal profile for each pollutant associated with a given source. This is an optional approach; if you do not want to use pollutant as a characteristic in assigning temporal profiles, you can put a “-9” in the pollutant field. In that case, all pollutants for a given source will be assigned that temporal profile.
The country/state/county code is defined as follows:
| 000000 = applies to all counties, states, and counties |
| Y00000 = applies to all states and counties in country Y |
| YSS000 = applies to all counties in state SS and country Y |
| YSSCCC = applies to county CCC in state SS and country Y |
