REGIONAL-SCALE ATMOSPHERIC MERCURY MODELING
Citation:
BULLOCK, R. REGIONAL-SCALE ATMOSPHERIC MERCURY MODELING. Presented at 31st Annual EPA-AWMA Information Exchange, Research Triangle Park, NC, December 05, 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:
This PowerPoint presentation gives a short synopsis of the state of the science of atmospheric mercury modeling, including a description of recent publications of model codes by EPA, a description of a recent mercury model intercomparison study, and a description of a synthesis paper on the source attribution of mercury deposition produced at the 8th Internation Conference on Mercury as a Global Pollutant.
