  • MEGANv3 update (Boyer)
  • List of possible QA steps from members
  • MEGANv2.1 simulation for 2016 possible?
  • Other agenda items

Minutes/Notes

  • Review minutes from last call
  • Action Items from last call addressed/reviewed:
    • WRF evaluation tech memo still a work in progress; will be available soon
    • BEIS3 tech memo (Vukovich) almost ready for workgroup to examine
    • CARB provide MEGAN comparison time series plots to the work group
    • QA steps were received from TCEQ and USEPA
    • Soil/fertilization NOx investigation added to the workgroup charge document
  • Vukovich gave an update on the BEIS3 model QA and documentation
  • Action Item: Vukovich to assemble list of QA steps into document and provide to workgroup for further examination/edits
  • Action Item: WRF evaluation tech memo will be forwarded to workgroup when it becomes available (USEPA)
  • Action Item: BEIS3 tech memo and BEIS3 input data to be shared with workgroup (USEPA)
  • Boyer (TCEQ) provided an update on MEGANv3: processed for specific days in July 2016 (July 17-19)
    • TCEQ mentioned that other days in 2016 could be examined
    • EPA provided BEIS3 output for these days as well
    • Action Item: Workgroup to provide a list of days/weeks that we should focus on where perhaps elevated ozone occurred in your region
    • TCEQ and CARB have had some contact with Alex Guenther (author of MEGAN)
    • TCEQ found that nitric oxide emissions were = 0 in MEGANv3
      • PhD student is working on new soil NOx WRF-CHEM-MEGAN version
      • Then will move this algorithm to MEGANv3 as well
      • Timing of this new soil NOx algorithm being available in MEGANv3 unknown
      • MEGANv3 may only have been evaluated in Texas region due to funding limitations
      • Discussion regarding concerns about MEGANv3 (pretty early version); Soil NOx algorithm issues
    • TCEQ listed some options with MEGANv3
      • options run MEGANv3 not use soil NOx, use MEGANv3 + BEIS NO
      • Run MEGANv2.1 for another option since MEGANv3 status unknown
  • Action Item: Jeremy to ask Alex about our timeline; MEGANv3 updates (soil NOx only update?)
  • Action Item: CARB and TCEQ to investigate if they can run MEGANv2.1 (USEPA may be backup plan)
  • Group mentioned that biogenic emissions modeling evaluations include running the AQ model
  • Action Item: Jeff to ask AQMG about air quality modeling plans for year 2016
  • Discussion on landuse improvements; Pima Co can provide updated landuse data maybe this summer
  • Tom Moore wanted to know if there are possible eco-region landuse improvements available
  • Action Item: Vukovich to ask EPA ORD about eco-region updates or any other possible upcoming landuse updates
  • Discussion about number of landuse types in BEIS3 and MEGANv3 and how to map them to landuse datasets
  • Action Item: CARB to try track down the MEGAN mapping to BEIS3 landuse paper (TX A&M)

Next Call: Tues Mar 20, 2PM EST

January 23, 2018

  • Review draft Charge Document for the Workgroup
  • BEIS3: 2016 emissions available
  • MEGAN version 3 - new version and plans
  • Need to set up regular meeting times for workgroup

Minutes/Notes

  • Overview of WG, 2016 EMP, and member introductions completed
    • Members were from states of CA, AZ, MT, GA, AL, TX, WRAP
      • members had various types of experience with biogenic emissions and AQ modeling
  • Reviewed Biogenic WG charge document
    • Discussion centered around the need to find field studies or sources of monitoring data to help with evaluation
      • Field studies: ORD
      • CARB (Jeremy): 2011 ISOP airborne monitoring campaign. Carried out comparisons with MEGANv2 and MEGANv3
      • NASA DISCOVER studies: data may be useful
    • Need list of QA steps for analyzing biogenic emissions datasets
    • Add investigation of fertilizer-nitric oxide (NO) emissions to charge document
    • Should we be concerned about Urban vegetation for biogenic emissions?
      • MEGAN has extra modeling step for incorporating urban veg (LAI incorporated)
    • Modeling resolution of 12km for this workgroup; some states may want to go to 4km
    • Request for evaluation tech doc of the 2016 WRF simulation
    • Tom Moore (WRAP) and Jeremy Avise (CARB) provided various biogenic emissions references for the workgroup to examine when possible.
  • Jeff Vukovich gave an overview of the BEIS3 simulation already carried out for year 2016
    • Technical documentation will be available soon on the BEIS3 simulation
    • Annual simulation at 12km resolution was completed for Carbon Bond 6 AQ modeling
  • Doug Boyer gave an overview of the MEGANv3
    • TCEQ sent the drives to LADCO to get MCIP data for 2016
    • See all the MEGANv3 tech docs Doug has provided on Biogenics WG Google site
    • GA and USEPA: would like to see April-October emissions from MEGANv3
  • Will have monthly conference calls on the 3rd Tuesday of every month at 2PM EST

Action Items
