[ES_JOBS_NET] Postdoctoral Research Scientist Position: High Resolution Aerosol Modeling

[Halley Thompson]

Postdoctoral Research Scientist Position: High Resolution Aerosol Modeling

Candidates are sought for a postdoctoral or similar position in aerosol
model evaluation based at NASA's Goddard Space Flight Center in Greenbelt,
Maryland. The position is under the supervision of Dr. Allison Collow
<https://science.gsfc.nasa.gov/sci/bio/allison.collow>, an associate
research scientist working on improving the representation of aerosols
within the Goddard Earth Observing System (GEOS) model. Research will be
conducted in support of NASA’s Global Modeling and Assimilation Office
(GMAO) <https://science.gsfc.nasa.gov/earth/gmao> in conjunction with
the Goddard
Earth Sciences Technology and Research II (GESTAR II)
<https://gestar2.umbc.edu/> consortium. The GMAO uses advanced modeling and
data assimilation techniques within the GEOS model to enhance NASA’s Earth
observations, support future suborbital and space-borne missions, and
conduct research aligning with NASA’s science priorities.


Highly-motivated early-career scientists with a background in atmospheric
science or a closely related science/engineering discipline are encouraged
to apply.


Research will focus on model evaluation of the aerosol lifecycle, including
emission, transport, and loss processes, in a stretched grid configuration
of GEOS with high spatial resolution over the United States. This
NASA-funded project will make use of satellite, airborne, and surface based
observational datasets to assess aerosol processes and make recommendations
for future improvements within the model. Emphases will be placed on the
representation of convective scavenging and wet deposition of aerosol
particles within GEOS as well as the emission and transport of dust along a
gradient in the model spatial resolution.


This is a grant-funded position. Continued funding is possible based on
availability and performance. Work will be completed onsite at NASA’s
Goddard Space Flight Center in Greenbelt, MD, with telework options
available.


Required Qualifications:

   -

   PhD in atmospheric science or closely related science/engineering
   discipline
   -

   Programming skills and experience
   -

   Excellent communication skills


Preferred Skills:

   -

   PhD in related field
   -

   Experience with Python, Fortran, and software versioning with Git

This position is administratively supported by UMBC and the GESTAR II
Consortium, which supports over 140 researchers based primarily at NASA
Goddard Space Flight Center. GESTAR II researchers work to create extensive
opportunities for breakthroughs in earth and atmospheric science research,
carrying out observational, experimental and theoretical research in
support of NASA strategic Earth Science mission objectives.


Goddard’s Earth Science Division is home to about 200 civil servants and
over 1200 collaborating researchers and support personnel, dedicated to
studying the Earth as an integrated system that includes the atmosphere,
oceans, biosphere, cryosphere, and geosphere. The Division operates as a
component of the Sciences and Exploration Directorate that collaborate on
interdisciplinary research with the Astrophysics Science, Heliophysics
Science, and Solar System Exploration Divisions.


The nominal starting date is mid-to-late 2026, but alternate dates are
possible depending on availability.


Candidates should provide a cover letter, CV (including publication list),
and a 3-page statement of research interests. Short-listed candidates will
be asked to supply three letters of reference at a later date. All
materials and inquiries should be sent by email with the Subject line:
Postdoctoral Researcher Position to: Allison Collow (allison.collow at nasa.gov
).


Completed applications received by May 29, 2026 will receive full
consideration, however the posting will remain open until the position is
filled.


Salary and benefits are competitive, commensurate with experience and
qualifications. UMBC and the GESTAR II consortium is committed to building
a diverse research community and encourages applications from women, racial
and ethnic minorities, individuals with disabilities and veterans. All
GESTAR II institutions are Equal Opportunity, Affirmative Action Employers.
As an institution that receives federal financial assistance, UMBC adheres
to Title IX and does not discriminate on the basis of sex. For more
