If the Summary Reporter is used to post-process MOVES output, the resulting emission inventories are incorrect when the following conditions are met:
dayID appears in the output (i.e., the output time aggregation on the Output Emissions Detail panel is set to Hour, 24-Hour Day, or Portion of Week
dayID is not selected in the list of "Categories" when specifying parameters for the Summary Report
In this case, the Summary Reporter will simply add the values corresponding to each dayID together without any weighting. However, when dayID is aggregated over, the resulting inventory is supposed to either represent a month's inventory (if monthID is retained) or an annual inventory (if monthID is also aggregated over)--and this requires additional weighting.
To correctly aggregate over dayID:
If the output time aggregation is Hour or 24-Hour Day, the emissionQuant values associated with dayID 2 (weekend days) need to be multiplied by 2, and the values associated with dayID 5 (weekday days) need to be multiplied by 5 to scale the inventories to the Portion of Week level
Then, the Portion of Week inventories need to be multiplied by the number of weeks in the month to scale the monthly level. The number of weeks in the month is calculated by dividing the number of days in the month by 7. For reference, MOVES stores this information in the monthofanyyear table in the default database.
In a future version of MOVES, the Summary Reporter will be updated to correctly aggregate over dayID, and it will issue warnings if you try to aggregate over dayID without all dayIDs, or aggregate over monthID without all monthIDs appearing in your output database.
