Research explores health impacts of urban living
<p>Research at ASU that could help decision-makers
address urban pollution problems and the impact of climate change on
urban environments is getting support from the National Science
Foundation (NSF).</p><separator></separator><p>Professor Alex Mahalov has been awarded a $775,000 grant from the NSF
for his regional climate research, which includes studies of urban
atmospheres and the health impacts of environmental stresses.</p><separator></separator><p>Such stresses – including urban heat islands, heat waves,
pollution and high levels of ozone – "negatively impact people's health
in the Valley," Mahalov said. "During periods of high levels of ozone,
for instance, more people with lung problems are admitted to hospitals."</p><separator></separator><p>Mahalov is a professor in the School of Mathematical and Statistical Sciences
in ASU's College of Liberal Arts and Science, and has a joint
appointment in the Center for Environmental Fluid Dynamics,
part of the School of Mechanical, Aerospace, Chemical and Materials
Engineering in the Ira A. Fulton Schools of Engineering.</p><separator></separator><p>His research project titled "Multi-Scale Modeling of Urban Atmospheres in a
Changing Climate" involves close collaboration with the National Center for
Atmospheric Research (NCAR) to be directed by Mohamed Moustaoui, an associate research scientist with the School of Mathematical and Statistical Sciences and the Center for Environmental Fluid Dynamics
.</p><separator></separator><p>The ASU-NCAR research team will develop nested models to simulate urban
atmospheres and their multiscale interactions with ambient climate and
atmospheric circulation occurring on urban scales. The models will be used to
explore the effects of large-scale atmospheric conditions on urban-scale
environment and climate, and the effects of the atmospheric conditions of
cities on the regions that surround them.</p><separator></separator><p>The project also will create research opportunities for ASU science and
engineering graduate students, who will be able to work with faculty on
the computational studies of complex urban systems.</p><separator></separator><p>In addition, ASU's High Performance Computing Initiative (HPCI) center
and Intel Corporation will provide advanced training in high-performance
computing and computational science to ASU students working with
project teams. The teams also will collaborate with HPCI and Intel on
adapting the computer simulation tools for use in next generations of massively parallelized multi-core architectures.</p><separator></separator><p>The HPCI center provides state-of-the-art computer facilities, software and
visualization capabilities to help researchers analyze and visualize data from
high-resolution computer simulations. The software will be used to provide
three-dimensional visualizations for ASU's Decision Theater.</p><separator></separator><p><em>Writer: Jessica Graham </em></p>
