Three-State Air Quality Study (3SAQS) Three-State Data Warehouse (3SDW) WSAQS 2011b Base Case Updates University of North Carolina (UNC-IE) ENVIRON International Corporation (ENVIRON) April 29, 2015
2011a CAMx Platform 36 km CONUS; 12 km WESTUS; 4 km 3SAQS 2011 NEIv1 emissions 2011 WSAQS O&G MOVES2010b Prelim PMDETAIL Fires 2011 WF, Rx and Ag MEGAN/WRAP Biogenics BCs from MOZART 2011 WRF 36/12/4 km Standard Configuration 2
2011b Updates 2011 NEI v2 Updated 2011 WSAQS O&G 2011 O&G for Williston/Great Plains Basins SMOKE-MOVES2014 for on-road mobile Updated 2011 fire emissions New WRF simulations for Winter Meteorology Address winter ozone events New BCs based on sensitivity tests Evaluate MOZART, GEOS-Chem and AM3 Wiki: http://vibe.cira.colostate.edu/wiki/wiki/2077/3saqs- 2011b-modeling-platform 3
2011b 2011 NEI Version 2 CEM Points Add IDs, missing points, hourly CEM data Non-CEM Points Move some to CEM; add missing ethanol facilities Commercial Marine Update to newer year data Non-Road Mobile Replace annual with monthly EI; Add Texas 2011 data On-Road Mobile (not used) EFs from MOVESTier3FRM 4
2011b 2011 O&G Emissions WSAQS update 2011 O&G emissions for D-J, Piceance, NSJ, SSJ, and Uinta Basins: EPA Tribal MNSR program data mined for information Addition of fracing engine emissions Wyoming O&G from WDEQ New O&G emissions for Williston and Great Plains Basins From BLM Montana/Dakotas Study by WRAP Remainder 2011 O&G from 2011 NEI v2 5
2011b SMOKE-MOVES2014 Use EPA MOVES2014/CB6 Emissions Factor Lookup Table w/ SMOKE-MOVES2014 State-specific data if provided to EPA 2011 36/12/4 km WRF data MOVES2014/CB6 not yet available Release with other updates as MOVES2014a in summer Preliminary results on wiki: http://vibe.cira.colostate.edu/wiki/wiki/1067/mov es2014-sensitivity-modeling-results 6
2011b Updated PMDETAIL Fires 2011a WRAP FETS fire emissions tool as used in JFSP DEASCO3/WestJumpAQMS 2008 modeling For 2011b use updated emission factors (EFs) and VOC/PM speciation updated (Akagi 2011; May 2014) Increases in VOC emissions Addition of HONO In addition, new fire emissions to support use of the Volatility Basis Set (VBS) SOA module VBS to be used in JFSP PMDETAIL Not WSAQS at this time
2011b WRF Winter Simulation 2011a 36/12/4 km WRF simulation followed configuration used in WestJumpAQMS with version updates Model evaluation was generally good http://vibe.cira.colostate.edu/wiki/Attachments/Modeling/3SAQS_2011_W RF_MPE_v8_draft_Aug04_2014.pdf One exception was winter ozone cold pool event WSAQS conducted revised winter 2011 WRF modeling 8 8
2011b Updated 36 CONUS BCs Evaluating 3 GCMs for BCs MOZART, GEOS-Chem and AM3 With and without using TOPCON BC Some have overstated dust (FCRS & CCRS) May have to cap dust BC concentrations Results from BC sensitivity tests will decide final BC for 2011b By end of May or early June 9
2011b 36/12/4 km CAMx Base Case Expect to be performed ~ July 2015 Include full MPE products Abbreviated report with online products 2020_2011b simulation Distribution on Data Warehouse 10
