Collaborative Air Quality Modeling in Iowa: Past Achievements and Future Objectives

Join the National RPO Modeling Discussion Group led by Chad Daniel from Iowa DNR to share information, tackle common issues, and foster collaboration between groups. Explore past accomplishments like species mapping, comparison methodologies, and addressing monitoring needs. However, challenges such as vertical layer collapsing, deposition velocity calculations, and more remain unresolved. The group aims to integrate efforts across RPOs, enhance coordination, and improve inter-group communications. Learn how to finalize meteorology, enhance inventory, improve model performance, and analyze techniques effectively. 8

  1. National RPO Modeling Discussion Group Past Efforts & Meeting Goals Chad Daniel Iowa DNR - Air Quality Bureau

  2. Group’s Purpose • Past • Share information • Identify common issues • Collaborate as necessary • Future • Continue the above • Integrate cross-group and RPO efforts wherever possible

  3. 2003 • Accomplishments • Model to monitor species mapping white paper • Model to monitor comparison methodologies white paper • Monitoring need “wish list” • Model tracking template • Information sharing

  4. Unresolved Issues • Issue specific technicalities… • Vertical layer collapsing • Deposition velocity calculations • Horizontal diffusion • Relative reduction factors • EI uncertainties • Being done piecemeal, RPO by RPO

  5. Meeting Goals • Integration • Within modeling discussion group • How to better coordinate efforts • Address specific technical questions • Between discussion groups • Improve inter-group communications • Between RPOs • Utilize forum to provide direction back to RPOs

  6. Upcoming issues • Finalizing meteorology • Inventory improvements and timing issues • Model performance • Post-processing analysis techniques • How can this forum attack these issues?
