DAY_SPECIFIC_YN: See description in Section 6.13.3.2, “Input Environment Variables”

FULLSCC_ONLY: See description in Section 6.2.3.2, “Input Environment Variables”. In this context, this option affects cross-referencing for the temporal cross-reference files by preventing left-7 SCC assignments.

USE_EXP_GEO_CODES: [default: N]

If set to Y then use GEOCODE_LEVEL[1-4] files instead of the COSTCY file to define expanded geographical detail such as country-level(GEOCODE_LEVEL1), country/state-level (GEOCODE_LEVEL2), country/state/county-level (GEOCODE_LEVEL3) or country/state/county/tribal-level (GEOCODE_LEVEL4).

HOUR_SPECIFIC_YN: See description in Section 6.13.3.2, “Input Environment Variables”

HOURLY_TPROF_BASE: [default: blank]

Defines the base of hourly temporal profiles. This flag is only applicable when hourly temporal profiles generated by Gentpro is available for Temporal to use. For a proper processing of hourly temporal profiles from Gentpro, user must let Temporal know the basis of hourly temporal profiles (i.e., hour of day, hour of month or hour of year). Gentpro outputs hourly temporal profiles IDs into temporal cross-reference input file ([A|M|P]TREF). See detail information at Section 8.3.2, “[A|M|P]TREF: Temporal cross-reference file”. If HOUR_PROFID column is filled by Gentpro, user must define the base of hourly profiles to correctly convert annual/monthly/daily inventories. If processing monthly inventory, user must set it to 'MONTH'.

OUTPUT_LOCAL_TIME: [default: N]

Defines whether the program processes daily/hourly inventories in local time or not.

OUTZONE: : [default: 0]

Indicates offset from Greenwich Mean Time (GMT) for episode start date and time. OUTZONE should be set to the standard time for the time zone of interest; SMOKE will adjust to Daylight Saving time for episodes that are during periods and in regions where Daylight Saving time applies.

Table 2.13, “Example OUTZONE settings and their associated time zones” provides allowed values for OUTZONE. The CMAQ model expects OUTZONE to be 0, while other models such as UAM-IV, UAM-V and CAM_X often use time zone 5. All models expect that the emissions and the meteorology data provided to the model will have a consistent time zone. SMOKE expects that the meteorology data will be in GMT.

Note that SMOKE expects OUTZONE to be set as a positive number for time zones in the Western Hemisphere, although standard notation would list these as negative values. For example, Eastern Standard Time is -5:00 hours from GMT, but OUTZONE for EST in SMOKE is 5.

RENORM_TPROF: [default: Y]

Defines whether Temporal normalizes the temporal profiles or uses them as they exist in the data file. If the profiles are specified as decimal values and sum to 1, then specify N. Otherwise, specify Y and the program will sum the values associated with each profile and then divide each value by the sum, thereby creating a normalized profile.

REPORT_DEFAULTS: See description in Section 6.2.3.2, “Input Environment Variables”

SMK_AVEDAY_YN: See description in Section 6.2.3.2, “Input Environment Variables”

SMK_EF_MODEL: [default:blank]

Name of the emission factor model to use. NOTE: User must set it to MOVES when processing activity inventory data (i.e., VMT, VPOP and SPEED).

SMK_MAXERROR: See description in Section 6.13.3.2, “Input Environment Variables”

SMK_MAXWARNING: See description in Section 6.13.3.2, “Input Environment Variables”

SMK_SOURCE: See description in Section 6.2.3.2, “Input Environment Variables”

UNIFORM_TPROF_YN: [default: N]

Defines whether to use uniform temporal profiles for all sources.

ZONE4WM: [default: Y]

Defines whether Temporal applies weekly and monthly temporal profiles using time zones. If SMOKE does not apply the profiles using the sources’ time zones, then all sources change from one day to the next or one month to the next at the same hour. This is what other emission processing systems have typically done, and it is a minor distinction in most cases.
