HUTZELL, W. T. AND D. J. LUECKEN. A53B-0199: PREDICTING THE FATE AND TRANSPORT OF TOXIC METAL EMISSIONS OVER THE UNITED STATES. Presented at 2006 Fall Meeting of the American Geophysical Union, San Francisco, CA, December 11 - 18, 2006.
Impact/Purpose:
The objectives of this task are to continue development and improvement of EPA's mesoscale (regional through urban scale) air quality modeling systems, such as the Community Multiscale Air Quality (CMAQ) model, as air quality management and NAAQS implementation tools. This task focuses on needed research and development of air quality models targeted for a major CMAQ model release in FY08. Model development for a broad scope of application is envisioned. For example, CMAQ will need to be able to simulate air quality feedbacks to meteorology and climate as well as intercontinental transport. The 2008 release of CMAQ is timed to coincide with EPA/OAR's and the states' needs for an improved model for assessments of progress (mid-course corrections) in the post-SIP submittal timeframe.
Description:
A poster presented at 2006 Fall Meeting of the American Geophysical Union on December 15th in San Francisco, CA. It discusses a regional photochemical model that determines the atmospheric concentration and deposition of toxic metals found in atmospheric particulate matter. It highlights an application of the model that simulates the transport and fate of the toxic metal emissions during 2001. Results are discussed and then compared to observations.
