  1. Using the EMF for Emissions Sensitivities and for CMAQ Alison M. Eyth Alexis Zubrow Qun He UNC Institute for the Environment October, 2008

  2. EMF Components • Data Management with Versioning • Quality Assurance • Tracking, automating of QA procedures • Case Management • Running SMOKE and other models • Control Strategy Development • Problem Tracking System • Surrogate and Speciation Tools Institute for the Environment

  3. EMF Architecture at EPA 4 CPU Application &Database Server Shared Disk SMOKE input files Data Management Case Management Quality Assurance Strategy Devel. Clients imports & exports data Compute Cluster starts and tracks runs SMOKE status messages and outputs Institute for the Environment

  4. Case Management • A Case stores information about SMOKE [and other model] runs • Summary attributes (i.e., metadata) • Inputs to programs • Program/Model Parameters • Jobs to run • Outputs from jobs • History and results of the runs • Should have all information needed to run programs and track results Institute for the Environment

  5. EMF-CMAQ Motivation • Goal to organize and track CMAQ runs • Easily see the relationships between SMOKE runs, CMAQ runs, and potentially post-processing runs • Track use of inputs/outputs between runs • Track physical location of inputs and outputs • Store settings for specific runs in centralized location • Easily view the detailed settings for related SMOKE runs and CMAQ runs Institute for the Environment

  6. CMAQ cases Institute for the Environment

  7. CCTM summary Institute for the Environment

  8. CCTM jobs Institute for the Environment

  9. CCTM inputs Env’t variables Institute for the Environment

  10. Related cases • Cases providing inputs or using outputs • Easily identified and accessed Institute for the Environment

  11. EMF cmd client EMF cmd client EMF cmd client EMF cmd client run JPROC run ICON run BCON run CCTM CMAQ-EMF Communication EMF server Database server status messages & outputs CMAQ cluster Institute for the Environment

  12. Emissions sensitivity tool motivation • Provide an ‘easy-to-use’ entry into the EMF • Allow modelers to set up and run emissions sensitivities based on SMOKE Cases previously run by the emissions modelers • Modelers will not need to be intimately familiar with all the details needed to set up the original cases • 2 use cases: adjust model-ready emissions and adjust source-level emissions Institute for the Environment

  13. Adjust Model-Ready Emissions Use Case • Adjust gridded model species emissions by a factor (increase or decrease) • Zero out runs • Combine emissions from different cases • Modified mrggrid to perform adjustments (SMOKE v2.5) • Adjust pollutant groups without worrying about speciation (e.g. VOC, HAPVOC, NOx) • Apply a geographic mask (e.g., to reduce only grid cells intersecting a state or states) • Delta adjustments (e.g., +/-5 tons) Note: Only SMOKE final merge (mrggrid) needs to be rerun – this requires the sector specific emissions from parent case Institute for the Environment

  14. Adjust Source-Level EmissionsUse Case • Adjust emissions by Sector and/or State/County/SCC or MACT or NAICS or Facility • e.g., Zero out or adjust emissions for a state for one or more SCCs, … • Reuses most SMOKE intermediate files • Need to run Cntlmat and Smkmerge for each affected sector • Emissions for adjusted sectors will be merged with non-adjusted sectors using mrggrid Institute for the Environment

  15. Creation of a Sensitivity Case Parent Case Sensitivity Template Case Summary tab, input datasets, parameter values Jobs, inputs, parameters Sensitivity Case (jobs, inputs, parameters) Values in sensitivity case are either matched and copied from parent case or provided by the user Institute for the Environment

  18. Sensitivity summary parent case Institute for the Environment

  19. Sensitivity jobs & inputs species, sector, factor NO, alm, 0.8 NO2, alm, 0.8 NO, onroad, 0.8 NO2, onroad 0.8 … Institute for the Environment

  20. Sensitivity outputs Institute for the Environment

  21. Future developments • CMAQ: • systematically set inputs and parameters for cases • capture outputs and messages when run CMAQ programs • Sensitivity tool: • Source-level SMOKE scripts modifications Institute for the Environment
