<div dir="ltr"><div class="gmail_extra"><p class="MsoNormal">I have a research opportunity available for a student or
postdoc during the summer of 2014 to work on organic aerosol modeling at the
EPA in Research Triangle Park, NC. The candidate will work on aerosol formation
from low-volatility compounds (SVOCs/IVOCs, semivolatile POA, etc) or aerosol
produced through aqueous pathways (IEPOX uptake, etc) with a focus on how
experiments and data are translated to model-ready parameterizations and
frameworks. A full description and instructions on applying are available
through ORISE: <a href="http://orise.orau.gov/epa/applicants/description.aspx?JobId=14533">http://orise.orau.gov/epa/applicants/description.aspx?JobId=14533</a>.
Participants will receive a monthly stipend. I plan to start reviewing
applications during the last week of January. Please encourage any interested
candidates with questions to contact me.
The project ID number is EPA-ORD/NERL-AMAD-2013-05.<b></b></p>

<p class="MsoNormal"><b>EPA-ORD/NERL-AMAD-2013-05</b></p>
<p class="MsoNormal"><b>Project Description:</b></p>
<p class="MsoNormal">A postgraduate project training opportunity is currently
available at the U.S. Environmental Protection Agency (EPA) National Exposure
Research Laboratory (NERL). This appointment is in the Atmospheric Modeling and
Analysis Division (AMAD) located in Research Triangle Park, North Carolina.</p>
<p class="MsoNormal"> </p>
<p class="MsoNormal">AMAD is responsible for developing the science and
algorithms that feed into the Community Multiscale Air Quality (CMAQ, <a href="http://www.epa.gov/amad/Research/RIA/cmaq.html">http://www.epa.gov/amad/Research/RIA/cmaq.html</a>)
model. CMAQ simulates both gas and aerosol-phase chemistry allowing for the
prediction of ozone and particulate matter with diameters less than 2.5 µm
(PM2.5) in the ambient atmosphere. The model functions as both a research tool
and decision support tool for air quality management plans.</p>
<p class="MsoNormal"> </p>
<p class="MsoNormal">Organic aerosol is a significant component of PM2.5 in the
United States. Traditionally, organic aerosols in models like CMAQ have been
treated as either primary (directly emitted) or formed due to reaction of
gas-phase volatile organic compounds. Since these types of models often fail to
reproduce observed concentrations in terms of the magnitude, diurnal variation,
and degree of oxidation, mechanisms for missing sources of organic aerosol have
been proposed. Two active areas of research include: oxidation of
low-volatility organic compounds and aqueous uptake pathways.</p>
<p class="MsoNormal"> </p>
<p class="MsoNormal">In collaboration with an AMAD mentor and other EPA team
members, the research participants may be involved in one or more of the
following training activities:</p>
<ul style="margin-top:0in" type="square">
<li class="MsoNormal">Comparing
traditional and volatility basis set (VBS) predictions of aerosol from the
CMAQ model</li>
<li class="MsoNormal">Examining
the role of semivolatile and intermediate volatility organic compounds
(S/IVOCs) in SOA formation including reconciling emission inventories of
primary organic aerosol with model-ready inputs</li>
<li class="MsoNormal">Investigating
the role of aqueous and in-cloud production of aerosol from soluble species
such as isoprene epoxydiols (IEPOX) or glyoxal</li>
<li class="MsoNormal">Contributing
to the 2015 public release of the next version of CMAQ</li>
</ul>
<p class="MsoNormal"> </p>
<p class="MsoNormal">Through their activities, the research participants will
gain an understanding of how experimental laboratory and field data are used to
parameterize models, how to evaluate those parameterizations, and/or how models
are applied to solve research and regulatory questions. The research
participants will have latitude in exercising independent initiative and
judgment in the research commensurate with the level of training. The research
participants may attend division seminars as well as other EPA presentations
and may present the results of their research at scientific conferences.</p>
