  • Next call scheduled for May 15 at 330PM ET

Minutes/Notes

  • Reviewed Action Items from last call
    • PAMS data has isoprene observations (Jeremy provided info)
    • LADCO and other agencies who will be doing AQ modeling at some point are aware that BEIS3 and MEGANv3 AQ sensitivity modeling is needed

  • MEGANv3 and BEIS3 gridded emissions are now available via a Colorado State
    • Contact Rodger Ames at Rodger.Ames@colostate.edu to get access to data
  • Boyer (TCEQ) obtained the MEGANv2-BEIS3 hybrid code from Texas A&M
    • In order to use this code for MEGANv3, software modifications are needed
    • CARB indicated that this Texas A&M code was used because MEGANv2 estimates could not be used in their estimation but this code allowed for a hybrid approach
    • Recommendation at this time is to table this code for possible future use but we do not have time to do hybrid modeling at this time
  • Kosty and Boyer (TCEQ) presented QA/comparisons for MEGANv3-BEIS3 for month of July 2016
    • Workgroup discussion included differences in diurnal profile of isoprene; investigation needed
      • MEGANv3 emissions start earlier and end later vs. BEIS3
      • CARB asked if TCEQ used stress adjustments in MEGANv3 run
        • TCEQ did not; CARB indicated that this functionality is new and they have done some sensitivities with it but not used it in modeling
        • Workgroup should learn more about these adjustments but no plan to use them in 2016 modeling at this time
    • Workgroup thought differences in LAI and landuse used in the two models needs to be investigated
      • Unsure how to extract landuse info out of MEGANv3 to compare vs. BELD4 (BEIS3 input)
    • Tom Moore will contact Ramboll about answering our MEGANv3 questions
    • Boyer to compile list of MEGANv3 questions from workgroup to give to Ramboll/MEGANv3 staff
    • MEGANv3 is in general is higher than BEIS3 for most states in July
      • Could be landuse, emissions factor or use of meteorological data differences
    • Boyer trying to obtain isoprene flux measurements from MN contact
    • Will need EPA ORD involved for BEIS3/BELD4 questions that come up
    • MEGANv3 does some sort of a MODIS-adjustment to landuse for urban areas; need more info
