*Description*

A postgraduate research training opportunity is currently available at the
U.S. Environmental Protection Agency's (EPA), Office of Research and
Development (ORD)/National Exposure Research Laboratory (NERL). This
appointment will be served with the Computational Exposure Division (CED)
in Research Triangle Park, NC.

Recent research has demonstrated a direct link between certain gas-phase
species found in the ambient atmosphere and organic aerosol phase
constituents. These linkages include isoprene epoxy diols (IEPOX) (e.g. Pye
et al., 2013) and organic nitrates (e.g. Pye et al., 2015) as major
particulate precursors. In addition to these direct links, a proper
representation of gas-phase chemistry is necessary to produce the right
balance of oxidants and later generation products that will determine
secondary organic aerosol (SOA) formation in air quality models. Currently,
CMAQ tends to overestimate ozone and underestimate organic aerosol in the
southeast U.S. As both these constituents (ozone and PM) are regulated by
the National Ambient Air Quality Standards (NAAQS), a good representation
of their formation in air quality models is critical for informed air
quality management.

The participant's research will focus on improving the Community Multiscale
Air Quality (CMAQ) model. He/she will use ambient measurements from recent
field campaigns (e.g. the Southern Oxidant and Aerosol Study (SOAS),
Southeast Atmosphere Study (SAS)) to improve the CMAQ model representation
of gas and aerosol-phase chemistry.

The research participant will learn how the Community Multiscale Air
Quality (CMAQ) model functions, post-processing of model data, and how to
use field or laboratory data to inform model development. He/she will also
learn how different aspects of atmospheric science (field, laboratory, and
modeling) interact.

This program, administered by ORAU through its contract with the U.S.
Department of Energy to manage the Oak Ridge Institute for Science and
Education, was established through an interagency agreement between DOE and
EPA.
*Qualifications*

A bachelor’s degree or higher in engineering, atmospheric science, or
chemistry within five years of the starting date, or completion of all
requirements for the degree should be expected prior to the start date.
Knowledge of a data processing/data analysis language (MATLAB, R, FORTRAN,
etc.) is desired. Applicants wishing to connect laboratory/ambient
measurements with model formulation are encouraged to apply.

The appointment is full time for three months and may be renewed upon
recommendation of EPA and contingent on the availability of funds. The
participant will receive a monthly stipend. Funding may be made available
to reimburse the participant’s travel expenses to present the results of
his/her research at scientific conferences. No funding will be made
available to cover travel costs for pre-appointment visits, relocation
costs, tuition and fees, or participant’s health insurance. The participant
must show proof of health and medical insurance. The participant does not
become an EPA employee.

The mentor for this project is Havala Pye (pye.havala at epa.gov). The desired
start date is June 15, 2016.
