Abstract:
The Community Modeling and Analysis System (CMAS) center was
established in cooperation with the U.S. Environmental Protection
Agency in 2001 to leverage the air quality modeling community’s
knowledge with regard to air quality modeling and analyses in order to
support policy maker decisions on air pollution control and regulation.
CMAS center is hosted by the University of North Carolina at Chapel
Hill. CMAS oversees the development, maintenance, training and support
of publicly available and scientifically sound air quality modeling
systems, as tools for decision support that are flexible and
user-friendly. Building upon the one-atmosphere concept, the modeling
systems are multi-scale, multi-pollutant with detailed descriptions of
atmospheric processes. The modeling systems are used to simulate
ambient air concentrations of pollutants such as ozone, particulate
matter, and toxic air pollutants. We will introduce highlights of CMAS
with particular emphasis on topics that are relevant to NCEP and WRF
development. Among those are the use of satellite data for model
evaluation; possible deployment of WRF-MM into various computational
platforms, evaluations and model inter-comparisons, outreach to
international and local community; and training. CMAS has a broad
spectrum of users both national and international. Those include users
from academic institutions, federal and state governments, private
sector, Regional Program Offices (RPOs) and environmental consulting
groups.
