SMOKE v2.0 Highlights • Support for all toxic source categories • SMOKE v1.5 supported nonroad and on-road mobile sources • SMOKE v2.0 adds support for non-point and point sources • Processes additional fields from the NIF (MACT, NAICS, source type code, and emission release point type) Carolina Environmental Program

  5. Toxics Support • New inventory format (ORL) for toxics data • Handles 8- and 10-digit SCCs within the same source category (non-point, nonroad, and point) • Revised controls to use MACT-based assignments • Can assign speciation profiles by MACT and SIC Carolina Environmental Program

  6. More on SMOKE v2.0 • Updates to SMOKE/MOBILE6 integration • First released in SMOKE v1.5 • Travel on freeway ramps accounted for when estimating freeway emissions • New settings for treatment of freeway speeds • Support for hourly speed profiles • Revised plume rise calculations • Changed terminology from “ozone season” to more general “average day” Carolina Environmental Program

  7. More on SMOKE v2.0 • Revised and expanded user’s guide • Had not been updated since SMOKE v1.4 • More introductory and conceptual material • Better explanations of directory structure and file locations • More detailed information on “nctox” release case • Updated for new programs, environment variables, and files Carolina Environmental Program

  8. SMOKE v2.0 Availability • Download executables, scripts, and data through the CMAS Model Clearinghouse http://www.cmascenter.org/modelclear.shtml • User’s guide available online at the main SMOKE website http://www.cep.unc.edu/empd/products/smoke/ Carolina Environmental Program

  9. Future Work • Additional quality assurance updates • Use humidity data from meteorology files when running SMOKE/MOBILE6 • Externally accessible code archive for better community collaboration • NIF-to-IDA converter Carolina Environmental Program

  10. Problems and Questions • Problems and questions can be submitted online through the CMAS Help Desk http://www.cmascenter.org/help.shtml • Uses the Bugzilla bug tracking system • Searchable archive of current and resolved issues Carolina Environmental Program
