    • 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
      • GAEPD provided 2016 ozone report that is on the workgroup's Google Drive
    • 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
      • QA of more months needed
    • Survey about which months to evaluate available; please complete ASAP
