CHING, J. K., V. ISAKOV, J. HERWEHE, AND M. A. MAJEED. INCORPORATING SUB-GRID VARIABILITY CONCENTRATION DISTRIBUTIONS WITH CMAQ. Presented at 4th Annual CMAS Models-3 User's Conference, Chapel Hill, NC, September 26 - 28, 2005.
Impact/Purpose:
The objective of this task is to develop and evaluate numerical and physical modeling tools for simulating ground-level concentrations of airborne substances in urban settings at spatial scales ranging from ~1-10 km. These tools will support client needs in the areas of air toxics and homeland security. The air toxics tools will benefit the National Air Toxics Assessment (NATA) program and human exposure modeling needs within EPA. The homeland security-related portion of this task will help in developing tools to assess the threat posed by the release of airborne agents. Both sets of tools will consider the effects induced by urban morphology on fine-scale concentration distributions.
Description:
This paper addresses a prototype demonstration of using fine scale modeling techniques for CMAQ application.
