LADCO Online Learning Center

LADCO hosts and co-sponsors webinars and online learning courses to help our members stay informed about advances in air pollution science and technology. Archives of recorded webinars and online courses are available on this page. Check our training calendar for upcoming online learning events.


March 20, 2019 EPRI Great Lakes Ozone Study

Richard McNider (U. Alabama at Huntsville) and Talat Odman (Georgia Tech)

Dr. Dick McNider of UAH presents his team’s work on improving WRF meteorology simulations over Lake Michigan. The purpose of their research was to optimize WRF for driving regional air quality model simulations. His analysis focuses on maximizing the skill of the model in simulating boundary layer dynamics over the lake. Dr. Talat Odman of Georgia Tech presents work on evaluating and improving CMAQ regional air quality model ozone simulations over Lake Michigan. He presents the results of a series of modeling experiments to test the model response to changes in emissions, photochemical mechanism, and ozone deposition rates.

December 20, 2018 Air Quality Modeling 101

Zac Adelman (LADCO)

This course will introduce students to photochemical grid modeling (PGM) and analysis. The different components of the PGM system, including meteorology, initial/boundary conditions, emissions, and chemistry-transport modeling will be explored through their relationships to estimating ground level air pollution concentrations. The key technical components of the PGM chemistry-transport model will be discussed in the context of the continuity equation, which is the fundamental governing equation of these models.

The input/output data flows, including how to generate or download data, data formats, and how to analyze the data will be discussed. Accessing, building, and running PGM software, and PGM analysis tools, will give the course participants a sense of the effort required to conduct modeling and analysis on their own. Finally the webinar will describe the limitations of PGMs and future directions for PGM development.

At the end of this webinar, the participants will have an understanding of the purpose of PGMs, how they work, what they can and can’t be used for, and what is involved in conducting modeling and analysis.
