SMOKE uses the most specific data available for any given source. For point sources, Temporal will read in the day-specific and hour-specific emissions and use these instead of the annual or average-day emissions that have been adjusted to hourly values. If both day-specific and hour-specific data are available for the same source, Temporal will use the hour-specific data. The settings that control the use of these emissions are HOUR_SPECIFIC_YN and DAY_SPECIFIC_YN.
