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

• https://drive.google.com/open?id=1iFqi0M8AUNKX36yQM9YNaPS8-gOLzA_8
• 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
• Next call scheduled for May 15 at 330PM ET
