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

12Institute for the Environment Emissions sensitivity tool motivation Provide an ‘easy-to-use’ entry into the EMF 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 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 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 2 use cases: adjust model-ready emissions and adjust source-level emissions

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

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