Emissions Inventories for WRAP Air Quality and Visibility Modeling


Descriptions of datasets used in compiling emissions inventories (EI) in support of air quality and visibility modeling are organized into the following tables.  Table 1 includes the most recent EI processing datasets and their QA results.   Table 2 lists the most recent EI datasets for CMAQ sensitivity cases.  EI datasets for CAMx are listed in Table 3.   Previously processed EI datasets are currently located in the archived session.  For more detailed information on emission inventories processing, please refer Chapter 2 of final 2005 report.  For further questions or comments, please contact Mohammad Omary.

2002 Natural Emissions Case (base02nt) In this sensitivity case, we employ only “natural” emissions in modeling domain background air quality conditions by excluding anthropogenic emission sources. This is to provide the regional model’s “floor” for analyzing future control strategies and reasonable progress on visibility at WRAP region Class I areas.

  • 2002 Dust emissions plots (monthly and yearly plots; posted on 4/24/06)
  • 2002 Base A Small Fire sensitivity (base02a_12k  with all fires.  vs. no Small Fires) In this sensitivity case, all small fires of less than 100 acres woodland and less than 300 acres grassland are removed. This is to determine whether small fires have significant visibility impacts.

    NOTE: All CAMx and PSAT Source Apportionemt modeling used the same emissions data that were used in CMAQ. The emissions were first processed in SMOKE for use in CMAQ and then converted to the CAMx emissions format. The emissions data are identical for CMAQ and CAMx with the exception that CMAQ species were converted into CAMx species.
