Introduction to AERMOD
Monday, November 13, 2017 from 8:00 am - 4:30 pm
Instructor: Michael Hammer, Lakes Environmental Software
Member $250/Non-Member $350
Note - Attendees are required to bring a laptop to fully participate in hands-on case studies.

This full-day course provides attendees with a full understanding of the AERMOD modeling system by balancing theory with hands-on, real world case studies. At the end of this course, participants should be able to understand the basics of regulatory air dispersion modeling for permit applications and risk assessments. Topics covered by this course include:
• Physics of air dispersion and atmospheric physics
• Meteorological pre-processing with AERMET
• Terrain processing with AERMAP
• U.S. EPA NAAQS overview
• Comparison of AERMOD to other models

Introduction to CAMx with Single-Source Discussion
Monday, November 13, 2017 from 8:00 am - 12:00 pm
Instructors: Ralph Morris and Bart Brashers,  Ramboll Environ

Member $150/Non-Member $250

This course will be a 4-hour overview of the Comprehensive Air Quality Model with extensions (CAMx; photochemical grid model (PGM) that will include an introduction to basic concepts of photochemical grid modeling  and more advanced discussion of issues associated with emerging applications (e.g., single-source ozone and secondary PM modeling). The course will provide a brief basic overview using a lecture-oriented presentation material on the basics of photochemistry and modeling; an introduction to CAMx, its features, data/computer requirements, probing tools, and new CAMx developments.  We will discuss how CAMx is used in the regulatory modeling process, such as  regional air quality planning for ozone, PM2.5 and regional haze State Implementation Plans (SIPs) and its use in supporting EPA national rules (e.g., ozone and PM2.5 transport rules).  The course will then go into a more detailed discussion of using CAMx, or other photochemical models, for single-source assessment modeling for ozone and secondary PM. A discussion of how EPA used CAMx for its Modeled Emission Rate Precursors (MERP) modeling and its implications for single-source modeling will be discussed.  We will also discuss the latest publicly available information on how the FLAG committee may recommend use of CAMx, or similar models, for assessing Air Quality Related Values (AQRVs) at Class I areas.  A comparison of CAMx with EPA’s Community Multiscale Air Quality (CMAQ) PGM will also be discussed, including the advantages and disadvantages of the two models. Issues related to the hands-on operation of CAMx will be presented (e.g., computer requirements, Windows vs. Linux, etc.), but actual hands-on training will not be included in this course.

Introduction to SCICHEM 3.1
Monday, November 13, 2017 from 1:00 pm - 5:00 pm
Instructors: Prakash Karamchandani, Ramboll Environ and Doug Henn, Xator Corp.
Member $150/Non-Member $250

This half-day course introduces SCICHEM, a non-steady state Lagrangian puff model that can be used to study the impact of single or multiple sources on primary pollutants as well as secondary pollutants, such as ozone and secondary PM2.5. With the upcoming Appendix W revisions, photochemical models with a complete treatment of gas-phase and aerosol chemistry will be the preferred method for a Tier 2 demonstration approach. Such models include photochemical grid models (PGMs), such as CMAQ and CAMx, as well as Lagrangian models, such as SCICHEM. SCICHEM includes chemistry modules comparable to those in CMAQ and CAMx for far field applications and secondary impacts, and an optimized chemistry scheme for near field applications for 1-hour NO2. The latest version of the model, SCICHEM 3.1, is publicly available on GitHub.

This course will provide a brief overview of the underlying dispersion model (SCIPUFF) and the treatment of chemistry in the model. Recent improvements in version 3.1 will be presented. This discussion will be followed by a presentation of examples for near-field (e.g., 1-hour NO2 concentrations) and far-field air quality impacts of primary and secondary pollutants (e.g., ozone and PM2.5). The secondary pollutant impacts calculated by SCICHEM will be compared with impacts calculated by PGMs. The course will conclude with a brief tutorial on conducting SCICHEM simulations for short-range and long-range impacts.
